Q. 52 The average age of a number of persons in a group was calculated as 35 years, which was 2.5 years more than the correct average as there was an error in recording the age of two persons as 38.5 years and 40 years instead of 29 years and 22 years respectively. The number of persons in the group was:
A. 11
B. 12
C. 15
D. 13
Answer: A.
Explanation:
Let the number of persons be x.
Wrong average = 35
Total age for wrong average = 35x
Correct average = 35 – 2.5 = 32.5
Total age for correct average = 32.5x
Correct age of two persons = 29 + 22 = 51
Wrong age of two persons = 38.5 + 40 = 78.5
Difference = 78.5- 51
35x – 32.5x = 27.5
x = 27.5/2.5 = 11

Q. 55 If x + y + z = 3, and x2 + y2 + z2 = 101, then what is the value of √(x3 + y3 + z3 − 3xyz)?
A. 19
B. 21
C. 24
D. 28
Answer: B.
Explanation:
x³ + y³ + z³ – 3xyz = (x+y+z) [(x + y + z)² – 3(xy + yz + zx)] —(1)
And,
(x + y + z)² = x² + y² + z² + 2(xy + yz + zx)
On put the values,
32 = 101 + 2(xy + yz + zx)
(xy + yz + zx) = -92/2 = -46
From the eq(1),
x³ + y³ + z³ – 3xyz = (3) [(3)² – 3(-46)] = 3 × 147 = 441
√(x3 + y3 + z3 − 3xyz )= √441 = 21
Q. 56 If 12x2 − 21x + 1 = 0, then what is the value of 9x2 + (16x2) −1?
A. 429/8
B. 465/16
C. 417/16
D. 453/8
Answer: C.
Explanation:
12x2 − 21x + 1 = 0
Divide by 4x,
3x − 21/4 + 1/4x = 0
3x + 1/4x = 21/4
On taking square,
(3x + 1/4x)2 = (21/4)2
9x2 + 1/16x2 + 2.3x.1/4x = 441/16
9x2 + 1/16x2 = 441/16 -3/4
9x2 + 1/16x2 = 417/16
Q. 57 A sum of ₹ x was divided between A, B, C and D in the ratio ⅓ :1/5 :1/6 :1/9. If the difference between the shares of B. and D. is ₹832, then the value of x is:
A. ₹7,592
B. ₹7,384
C. ₹7,696
D. ₹7,488
Answer: A.
Explanation:
Ratio of A, B, C and D =⅓ :1/5 :1/6 :1/9 = 30 : 18 : 15 : 10
Let the share of A, B, C. and D. be 30p, 18p, 15p and 10p.
The difference between the shares of B. and D. = 832
18p – 10p = 832
p = 832/8 = 104
x = 30p + 18p + 15p + 10p = 73p
x = 73×104 = Rs.7592

Perimeter = 6a = 6×40 = 240 m
The cost of fencing the field = 240×16.8 = Rs.4032
Q. 59 Places A and B are 144 km apart. Two cars start simultaneously, one from A and the other from B If they move in the same direction, they meet after 12 hours, but if they move towards each other they meet after 9/8 hours. The speed (in km/h)of the car moving at a faster speed, is:
A. 70
B. 72
C. 60
D. 64
Answer: A.
Explanation:
Speed of faster car = v1
Speed of slower car = v2
Case I: Cars travel in same direction
144 km distance covered in 12 hours so,
Relative speed = v1 – v2
v1 – v2 = 144/12 = 12 —(1)
Case II: Cars in opposite direction
144 km distance covered in 9/8 hours so,
Relative speed = v1 + v2
v1 + v2 =144/ 9/8= 128 —(2),
From eq(1) and (2),
2v1 = 12 + 128
v1 = 140/2 = 70 km/hr
The speed of faster car is 70 km/hr.
Q. 60 A, B and C donate 8%, 7% and 9%,of their salaries, respectively to a charitable trust. The salaries of A and B are same and the difference between their donations is ₹259. The total donation of A and B is ₹1,185 more than that of C. The total donation of A and C is what percentage of the total salaries of A, B and C? (Correct to one decimal place)
A. 6.2%
B. 5.8%
C. 6.4%
D. 7.1%
Answer: B.
Explanation:
Let the salaries of A, B and C be x, x, y.
Donation of A, B and C = 0.08x, 0.07x and 0.09z
Difference between donations of A and B = 259
0.08x – 0.07x = 259
x = 259/0.01 = 25900
Total donation of A and B = donation of A + 1185
0.08x + 0.07x = 0.09z + 1185
0.15x = 0.09z + 1185
0.09z = 0.15×25900 – 1185 = 2700
z = 2700/0.09 = 30000
Total donation of A and C = 0.08x + 0.09z
=0.08×25900 + 2700 = 2072 + 2700 = 4772
Total salaries of A, B and C = 25900 + 25900 +30000 = 81800
Required percentage = 4772/81800× 100 = 5.8%

Four men and 6 women can complete a certain piece of work in 5 days whereas three men and 4 women can complete it in 7 days so,
(4m + 6w) ×5 = (3m + 4w) × 7
20m + 30w = 21m + 28w
m = 2w
Now,
Work = 2½ times the same work
Work = 5/2× same work
(m/w)× 5 = 5/2 ×(4m+6w)× 5
w× 5 = 5/2 ×(4×2w+6w)× 5
w× 5 = 5/2 ×14w× 5
w = 35
So need for worker = 25w + 10w
Number of man = 10 m/2 = 5 man
Q. 62 In △ABC, ∠B = 72∘ and ∠C = 44∘. Side BC is produced to D. The bisectors of ∠B and ∠ACD meet at E. What is the measure of ∠BEC ?
A. 58∘
B. 46∘
C. 32∘
D. 36∘
Answer: C.
Explanation:
In △ABC,
∠A + ∠B + ∠C = 180°
∠A = 180 − 72 − 44 = 64°
By angle bisector property,
∠BEC = ∠A / 2
∠BEC = 64° / 2 = 32°
Q. 63 In △ABC, AC = 8.4cm and BC = 14cm. P is a point on AB. such that CP= 11.2 cm and ∠ACP = ∠B. What is the length (in cm) of BP?
A. 4.12
B. 2.8
C. 3.78
D. 3.6
Answer: C.
Explanation:
ΔACP ~ ΔABC
∵ ∠ACP = ∠B ( A is common and )
BP = AB. – AP = 10.5 – 6.72 = 3.78 cm
Q. 64 If 2x2 + y2 + 8z2 − 2 2xy + 4 2yz − 8zx = (Ax + y + Bz)2 , then the value of (A2 + B2 − AB) is:
A. 16
B. 14
C. 6
D. 18
Answer: C.
Explanation:
2x2 + y2 + 8z2 − 2√2xy + 4√2yz − 8zx = (Ax + y + Bz)2
= 2x2 + y2 + 8z2 + 2(−√2xy − 2√2yz + 4zx) = (Ax + y + Bz)2
= 2x2 + y2 + 8z2 + 2(−√2x.y − y.2√2z + 2x.2√2z) = (Ax + y + Bz)2
= (+√2x − y + 2√2z)2 = (Ax + y + Bz)2
Ax = √2x
A = √2
y = -1
B = 2√2
Now,
(A2 + B2 − AB)
((√2)2 + (2√2)2 − √2.2√2)
= 2 + 8 – 4 = 6
Q. 65 How many numbers are there from 200 to 800 which are neither divisible by 5 nor by 7?
A. 407
B. 410
C. 413
D. 411
Answer: D.
Explanation:
Total numbers = (800 – 200) + 1 = 601
Number of terms which divide by 5
l = 800
a = 200
Common difference(d) = 5
l = a + (n-1)d
800 = 200 + (n – 1)5
n-1 = 120
n = 121
Number of terms which divide by 7
l = 798
a = 203
Common difference(d) = 7
l = a + (n-1)d
798 = 203 + (n – 1)7
n-1 = 85
n = 86
Number of terms which divide by 5 and 7
l = 770
a = 210
Common difference(d) = 35
l = a + (n-1)d
770 = 210 + (n – 1)35
n-1 = 16
n = 17
Number of terms which divide by either 5 or 7 = 121 + 86 – 17 = 190 Number of terms which divide by neither 5 nor 7 = 601 – 190 = 411

A. 14 3/7
B. 17 1/3
C. 16 2/3
D. 14 2/7
Answer: C.
Explanation:
Total production of all types of motorcycles in 2014 = 84 + 87 + 89 + 100 = 360 Total production of all types of motorcycles in 2018 = 98 + 92 + 110 + 120 = 420 = 420−360/360 × 100 = 60/360 × 100 =16 ⅔.
Q. 68 By what percentage is the total production of type A. motorcycles over six years, less than the total production of all types of motorcycles in 2013 and 2016?
A. 32.2
B. 32.8
C. 31.6
D. 30.5
Answer: D.
Explanation:
Total production of type A. motorcycles over six years = 95+ 84 + 85 + 89 + 80 + 98 = 531
total production of all types of motorcycles in 2013 and 2016 = 95+ 98 + 104 + 103 + 89 + 88 + 92 + 95 = 764
Required percentage =764−531/764 ×100 =233/764 ×100 = 30.5%

Q. 69 Two circles of radii 7 cm and 5 cm intersect each other at A. and B, and the distance between their centers is 10 cm. The length (in cm) of the common chord AB is:
A. (3√66 )/5
B. (4√66)/5
C. (2√74)/ 5
D. (3√74)/ 5
Answer: B.
Explanation:
AP = 5 cm
AQ = 7 cm
PQ = 10 cm
Let the CQ be x. So,
PC = 10 – x cm
△ACQ is right angle triangle so,
(AQ)2 = (AC)2 + (CQ)2
(7)2 = (AC)2 + (x)2
(AC)2 = 49 − (x)2 —(1)
△APC is right angle triangle so,
(AP)2 = (AC)2 + (PC)2
(5)2 = (AC)2 + (10 − x)2
(AC)2 = 25 − (10 − x)2 —(2)
From eq(1) and (2)
49 − (x)2 = 25 − (10 − x)2
24 − (x)2 = −(10 − x)2
(x)2 = 24 + 100 + x2 − 20x
20x = 124
x = 124/20 = 6.2 cm
From eq(1),
(AC)2 = 49 − (6.2)2
(AC)2 = 49 − 38.44
(AC)2 = 10.56 = 1056/100 = 264/25
AC = (2√66)/5
The common chord AB = 2 ×(2√66)/5 = (4√66)/5
Q. 70 If the selling price of an article is 8% more than the cost price and the discount offered is 10% on the marked price of the article, then what is the ratio of the cost price to the marked price?
A. 5 : 6
B. 8 : 9
C. 3 : 4
D. 4 : 5
Answer: A.
Explanation:
Profit = 8%
Let the cost price be Rs.100.
Selling price = 108
Discount on marked price = 10% so,
selling price = 100 – 10 = 90%
90% = 108
Marked price(100%) =108/ 90 ×100 = Rs.120
Ratio of the cost price to the marked price = 100 : 120 = 5 : 6
Q. 71 The given table represents the production of different types of motorcycles (in thousands) over a period of six years. Study the table carefully and answer the question that follows.
What is the ratio of the total number of motorcycles of type B. produced in 2016 and 2018 to the total number of motorcycles of type D. produced in 2013, 2015 and 2016?
A. 1 : 2
B. 3 : 4
C. 3 : 5
D. 2 : 3
Answer: C.
Explanation:
Total number of motorcycles of type B. produced in 2016 and 2018 = 88 + 92 = 180
Total number of motorcycles of type D. produced in 2013, 2015 and 2016 = 103 + 102 + 95 = 300
Ratio of the total number of motorcycles of type B. produced in 2016 and 2018 to the total number of motorcycles of type D. produced in 2013, 2015 and 2016 = 180 : 300 = 3:5
Q. 72 A sum of ₹8,000 invested at 10% p.a. amounts to ₹9,261 in a certain time, interest compounded half-yearly. What will be the compound interest (in ₹) on the same sum for the same time at double the earlier rate of interest, when interest is compounded annually?
A. ₹2,520
B. ₹2,480
C. ₹2,560
D. ₹2,500
Answer: C.
Explanation:
for half yearly,
rate(r) = 10/2 = 5
p = 8000
Amount = 9261
Amount = p(1 + r/100 )t
9261 = 8000(1 +5/100 )t
(9261)/(8000) =(105/100 )t
(21/20)3 =(21/20 )t
t = 3 years
Time = 3/2 years
Now,
r1 = 2r = 2 ×10= 20
Compound interest = p(1 + r/100 )t − p
= 8000(1 +20/100 )3/2 − 8000
= 8000×6/5×(6/5)1/2 − 8000
= 10560 – 8000 = Rs.2560
Q. 73 A sells an article to B. at a loss of 20%, B sells it to C at a profit of 12.5% and sells it to D at a loss of 8%. If D buys it for ₹248.40, then what is the difference between the loss incurred by A and C?
A. ₹36.80
B. ₹38.40
C. ₹42.60
D. ₹39.20
Answer: B.
Explanation:
Cost price for D = 248.40
Loss for C = 8%
Cost price for C = 248.40 × 100/92 = 270
Loss of C = 270 – 248.4 = 21.6
Selling price for B = Rs. 270
Profit = 12.5%
Cost price for B = 270 ×100/112.5 = 240
Selling price for A = Rs. 240
Loss = 20%
Cost price for A = 240 × 100/80= 300
Loss for A = 300 – 240 = 60
Difference between the loss incurred by A and C = 60 – 21.6 = Rs. 38.4
