|A) 7 lts||B) 14 lts|
|C) 98 lts||D) 42 lts|
To know the the measuring cylinder that can fill all the given capacities , they must be divisible by the required number.
98,182,266 all are divisible by 14
So 14 litres is the largest cylinder that can fill all the given cylinders.
The other method is take HCF of all given capacities i.e 98, 182 and 266.
