Question

two tankers contain 850 liters and 680 liters of petrol respectively.find the maximum capacity of a container which can measure the petrol of either tank in exact number of liters.

Answer 1

first we have to find the hcf of 850 and 680 
so,
850=(680*1)+170
170=(170*3)+170
170=(170*1)+0
⇒hch of 850 and 680 is 170
∴the maximum capacity of ac container which can measure the petrol of either tank in exact number of liters is 170
