Question

 A’s efficiency is 60% of B’s. If B alone can complete a job in 30 days, find the number of days A will take to do the same job​

Answer 1

Answer:

Step-by-step explanation

A = 60 % of B

--> A = .6B

--> if B takes 30 days then A must take more than 30 days because his efficiency is less than B

so A will take 30/.6 days = 50 days
