Question

Two tankeres contain 850 literes and 680 litres of petrol respectively find the maximum capacity of a container which can measure the petrol of either tanker is exact no of times

Answer 1

the maximum capacity of a container which can measure the petrol of either tank is the HCF of 850 and 680.
so,
850=680×1+170
680=170×4+0
so,
HCF = 170
hence, the maximum capacity of the container is 170l.
