Question

75 liters of kerosene oil and 25 liters of petrot have to be kept in tins of identical size such two
kinds of oil do not get mixed. How many tins will be required at least? How much oil will each tin
hold?​

Answer 1

Answer:

4 cans.

Explanation:

we have to keep 75l of kerosene oil and 25l of petrol in seperate identical tins

since we have to use the least number of cans, the capacity of each can has to be the HCF of 75 and 25 = 25l

by using 25l cans, kerosene oil can be kept in 3 cans and petrol can be kept in 1 can. thus, 4 cans are required at least.
