1. C and D
2. A and B
3. A
4. B

Answer 1

Correct Answer - Option 2 : A and B

Given:

Speed of bus without stoppage = 48 km/h

Speed of bus with stoppage = 36 km/h

Calculation:

With stoppages bus covers (48 – 36) = 12 km less per hour

To cover 12 km

Time = (12/48) × 60 = 15 min per hour

A. 15

A is correct.

B. (3/8) of (5/6) of 48

⇒ (15/48) × 48

⇒ 15

B is correct.

∴ A and B are correct.
