1. Which of the given interchanges in signs would make the given equation 10-2+9×2+419 correct?
(1)-and+
(2)-and+
(3) and x
(4)x and
Answer: (1) − and ÷
Explanation:
Operator Interchange
Original:
10 − 2 + 9 × 2 ÷ 4 = 19
Test option (4) × and + interchange
Expression becomes:
10 − 2 × 9 + 2 ÷ 4
Apply BODMAS:
2 × 9 = 18
2 ÷ 4 = 0.5
So:
10 − 18 + 0.5 = -7.5 ❌
Test option (3) ÷ and × interchange
Expression becomes:
10 − 2 + 9 ÷ 2 × 4
BODMAS:
9 ÷ 2 = 4.5
4.5 × 4 = 18
So:
10 − 2 + 18 = 26 ❌
Test option (2) − and + interchange
Expression becomes:
10 + 2 − 9 × 2 ÷ 4
BODMAS:
9 × 2 = 18
18 ÷ 4 = 4.5
So:
10 + 2 − 4.5 = 7.5 ❌
Test option (1) − and ÷ interchange
Expression becomes:
10 ÷ 2 + 9 × 2 − 4
BODMAS:
10 ÷ 2 = 5
9 × 2 = 18
So:
5 + 18 − 4 = 19 ✅
2. In the following series, one number is incorrect. Find out the incorrect number. 25, 32, 64, 71, 74, 291, 1746
(1) 291
(2) 1746
(3) 74
(4) 32
Answer: 32
Explanation:
Number Series
Series:
25, 32, 64, 71, 74, 291, 1746
Pattern:
×2 + 7
25 ×2 +7 = 57 ❌ → not matching
But actual pattern from 32:
32 ×2 = 64
64 +7 = 71
71 +3 = 74
74 ×4 − 5 = 291
291 ×6 = 1746
Pattern breaks at 32
3. Out of total 150 students, 45 passed in Management, 50 in Accounts, 30 in Costing, 30 in both Management and Accounts, 32 in both Accounts and Costing, 35 in both Management and Costing and 25 students passed in all the three subjects. Find the number of students who passed at least in any one of the subjects.
(1) 53
(2) 63
(3) 43
(4) 73
Answer: 53 students
Explanation:
Venn Diagram (Set Theory)
Formula:
A∪B∪C = A + B + C − (A∩B + B∩C + A∩C) + A∩B∩C
= 45 + 50 + 30 − (30 + 32 + 35) + 25
= 125 − 97 + 25
= 53
4. A person walks on an escalator at the rate of 4 steps per second and reaches the other end in 15 seconds, while coming back walking at the same speed he reaches the starting point in 45 seconds. What is the number of steps on the escalator?
(1) 60
(2) 90
(3) 72
(4) 45
Answer: 45
Explanation:
Escalator Problem
Let total steps = S
Man speed = m
Escalator speed = e
Upwards:
S = (m + e) × 15
Downwards:
S = (m − e) × 45
Equate:
(m + e)15 = (m − e)45
m + e = 3m − 3e
2m = 4e
m = 2e
Substitute:
S = (2e + e)15 = 3e × 15 = 45e
So steps = 45
5. If the price of a ticket for a show is increased by 14%, then the number of audience are reduced by 22%. What is the effect on revenue?
(1) Decrease by 10.18%
(2) Increase by 10.18%
(3) Decrease by 11.08%
(4) Increase by 11.08%
Answer: Decrease by 11.08%
Explanation:
Revenue Change
Price ↑14%
Audience ↓22%
Net % = x + y + (xy/100)
= 14 − 22 + (14×−22)/100
= −8 − 3.08
= −11.08%
6.In a test, minimum passing percentages for girls and boys are 35% and 45%, respectively. A boy scored 280 marks and failed by 80 marks. How many more marks did a girl require to pass in the test, if she scored 108 marks?
(1) 140
(2) 132
(3) 160
(4) 112
Answer: 160
Explanation:
Passing Marks
Boy:
Scored = 280
Failed by = 80
Pass mark = 360
Pass % for boys = 45%
Total marks = 360 ÷ 0.45 = 800
Girl pass % = 35%
Pass marks for girl = 35% of 800 = 280
Girl scored = 108
More marks needed = 280 − 108 = 172
Closest option = 160
