Question

Speed of A is 50% more than B and B alone require 20 days to do certain amount of work so how much time A and B together require

Answer 1

Answer:

A and complete work together in 16 days.

Step-by-step explanation:

Given ,

A work 50% faster than B

B complete work in 20 days.

Suppose total work is 20.

So

B complete 1 work per day

So A is 50% faster than B

A complete 1.5 work per day.

So A+B = 2.5 work/day

So,

20 works complete in (20/2.5) = 16 Days.
