Ashish can do 1/2 of a work in 10 days and Karthik can do 1/3rd of the same work in 8 days. What is the ratio of their capacities ?

4 : 7

6 : 5

5 : 6

7 : 4

Solution: Ashish : 1/2 of work in 10 days => full work in 20 days. Karthik : 1/3 work in 8 days => full work in 24 days. Ratio of their capacities = 24 : 20 = 6 : 5.
