Question

two tankers contain 850 liters and 680 liters of petrol respectively.find the maximum capacity of ac 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 

Answer 2

170 ......................................
