Question

Ram can do work 15 days,rahim is 50 % more efficient than ram,rahim can do work how much days

Answer 1

Ram can do whole work in 15 days

Let Rahim can do the work in Χ days

As Rahim is 50% more efficient than Ram, then he can do the work more faster than Ram.

Let total work be 1 part.

∴ Ram's 1 day work = 1/15 part

∴ Rahim's 1 day work = 1/15 +(1/15 × 50)100

= 1/15 + 1/30

= 1/10 part

∴ Rahim's can do 1 part work in 1÷1÷10 days.

= ( 1× 10 )÷1

= 10 days.
