40
55
60
45
Correct answer
55
Why this answer is correct

100 - 10 = 90
90 - 15 = 75
75 - 20 = 55
55 - 25 = 30
Hence, the correct answer is “Option 2”.

18-81, 27-729, 15-225, 12-144 - which pair is odd?
27-729
18-81
15-225
12-144
Correct answer
18-81
Why this answer is correct
Logic: (First Number)2 = Second Number
For 27-729:
272 = 729
For 18-81:
182 = 324 ≠ 81
For 15-225:
152 = 225.
For 12-144:
122 = 144.
Therefore, the odd pair is 18-81.
Hence, the correct answer is “Option 2”.

Correct answer
30
Why this answer is correct
BODMAS Table:
Given equation: (60 ÷ 6) × 4 - 10 = ?
⇒ (60 ÷ 6) × 4 - 10 = ?
⇒ 10 × 4 - 10 = ?
⇒ 40 - 10 = ?
⇒ 40 - 10 = ?
⇒ 30.
Hence, the correct answer is "Option 3".
If # means addition, * means subtraction, @ means multiplication, and % means division, evaluate 10 # 6 \% 2 * 3 .
13
14
10
12
Correct answer
10
Why this answer is correct
BODMAS Table:
Given equation: 10 # 6 % 2 ∗ 3 = ?
| # | * | @ | % |
|---|---|---|---|
| + | - | × | ÷ |
Now, replacing the symbols:
⇒ 10 + 6 ÷ 2 - 3 = ?
⇒ 10 + 6 ÷ 2 - 3 = ?
⇒ 10 + 3 - 3 = ?
⇒ 10 + 3 - 3 = ?
⇒ 13 - 3 = ?
⇒ 10.
Hence, the correct answer is "Option 3".
If @ means addition and * means multiplication, find .
Correct answer
Why this answer is correct
BODMAS Table:
Given equation: 3 * 4 @ 2 = ?
| @ | * |
|---|---|
| + | × |
Now, replacing the symbols:
⇒ 3 × 4 + 2 = ?
⇒ 3 × 4 + 2 = ?
⇒ 12 + 2 = ?
⇒ 14.
Hence, the correct answer is "Option 2".
A can complete the work in days and B in days. They work together for days, then B leaves and A finishes the rest alone.
How many total days are required to complete the work?
Correct answer
Why this answer is correct
Given:
Time taken by A = 20 days,
Time taken by B = 25 days,
Work together for 5 days.
Formula Used:
Total Work = Efficiency × Time.
Efficiency = Total Work ÷ Individual Time.
| Person | Days | Total Work (LCM) | Efficiency |
|---|---|---|---|
| A | 20 | 100 | 5 |
| B | 25 | 4 |
⇒ Combined Efficiency of A and B = 5 + 4 = 9 units/day.
⇒ Work completed by both in 5 days = 9 × 5 = 45 units.
⇒ Remaining Work = 100 − 45 = 55 units.
⇒ Time taken by A alone to finish remaining work = 55 ÷ 5 = 11 days.
⇒ Total days to complete the work = 5 (together) + 11 (A alone) = 16 days.
Hence, the correct answer is “Option 2”.
