Question

kamal can do a piece of workin 15 days.bimal is 50% percent more efficient than kamal in doing the work. in how many days will bimal do that work?

Answer 1

Kamal does a work in = 15 days

So, in 1 day Kamal will do = 1/15 work

Bimal is 50% more efficient than Kamal

This means that Bimal will do 50% more work in 1 day than Kamal

Or, we can say, Bimal will do 150% work of Kamal in 1 day

So, Bimal will do

= 1/15 x 150/100 work in 1 day

= 150 / 1500 work in 1 day

= 1/10 work in 1 day

therefore, Bimal will do that work in 10 days
