Solution

The correct option is D 170 litres
Maximum capacity of the measuring vessel = HCF (850, 680)

We use Euclid's division algorithm to find the HCF of 850 and 680.

850 = 680 × 1 + 170
680 = 170 × 4 + 0

HCF (850, 680) = 170
So, the maximum capacity of the measuring vessel required is 170 litres.
