Question

190. A merchant has 120 litres of oil of one kind, 180 litres of another

kind and 240 litres of a third kind. He wants to sell the oil by filling

the three kinds of oil in tins of equal capacity. What should be the

greatest capacity of such a tin?​

Answer 1

Answer:

60 litres

Step-by-step explanation:

We need to find the HCF or GCD that is Greatest Common Divisor 

120=23×3×5

180=22×32×5

240=24×3×5

GCD=22×3×5=60

The greatest capacity = 60 liters

So the merchant needs to fill 60 liters of all types of oils
