Explanation

The difference in their ages is 33 years, so:

7x - 4x = 33

3x = 33

x = 11

Now, we can find Zaid's age:

Zaid's age = 4x

= 4 × 11

= 44 years

Explanation

The CP of the gun = Rs. 2500

The SP of the gun = Rs. 900

The loss is = CP - SP = Rs. ( 2500 - 900 )

= Rs. 1600

Hence, the loss incurred by Akbar is 64%.

Explanation

Loss = 50000 - 43000 = 7000

Loss % = (7000 / 50000) × 100 = 14%

Explanation

To find the percentage, divide 25 by 75 and multiply by 100:

25 ÷ 75 = 0.33

0.33 × 100 = 33%

Explanation

Given:

• Speed of train = 120 km per hour

• Time = 8 hours

Formula

Distance = Speed × Time

Distance = 120 × 8

= 960 km

Explanation

Loss = Cost Price - Selling Price

= 90,000 - 80,000 = Rs. 10,000

Percentage Loss = (Loss / Cost Price) × 100

= (10,000 / 90,000) × 100 = 11.11%

Explanation

48 → 45 (−3)

45 → 40 (−5)

40 → 33 (−7)

33 → 24 (−9)

Now continue the pattern: next difference should be −11

24 − 11 = 13

Explanation

• "I have no brother": This means the man is an only child.
• "That girl's father is my father's son": This means the girl's father is the man himself.

Therefore, the photograph was of his daughter.

So the correct answer is (C) His daughter.

Explanation

The car travels 30 km in the first hour and 32 km in the second hour, total distance = 30 + 32 = 62 km.

Total time = 2 hours, so average speed = 62 ÷ 2 = 31 km/h.

Explanation

If they sold 25% of the lights, they have 75% of the lights left. We are given that 75% of the lights is 1500:

$$0.75x=1500$$

Solve for $x$:

x=1500/0.75

​=2000

So, the total number of lights initially was 2000.
