4. 14, 25

Answer 1

Correct Answer - Option 3 : 3, 5

Given:

3 cars distance covered from A to B + 2 cars distance covered from A to C = 19

Calculation :

Let distance between the A to B and A to C be a km and b km respectively.

⇒ 3a + 2b = 19

⇒ a + b = 8

Solving,

⇒ a = 3

⇒ b = 5

∴ distance between A to B and A to C is 3km and 5km respectively.
