Question

Two tankers contain 200 litres and 440 litres of petrol respectively.
The maximum capacity of a container which can measure the petrol of either tank in the exact number of times is ____ litres.

• A. 20
• B. 30
• C. 40
• D. 50

Answer 1

The correct option is C 40

We need to find the HCF of 200 and 440 to find the maximum capacity of a container which can measure the petrol from either tank.

Factors of 200: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
Factors of 440: 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

Hence, HCF of 200 and 440 is 40.

$\therefore$ The maximum capacity of a container is 40 litres.
