Answer 1

Answer:

10 Days

Step-by-step explanation:

let A do work in 15 days at the speed of x per day

WORK = 15*x

same work is done by B in how much time is your question

let time be t, given that efficiency is 50% more which means he x/2 speed more than A

total speed at which work done in one day for B is 3x/2.

WORK =(3x/2)*t

put the value of work from above

15x=1.5xt x is cancelled out by x and your answer is

t=15/1.5

t=10 days

HOPE IT HELPS

Answer 2

I think in 7.5 days

Step-by-step explanation:

As B is 50% more efficient than A so B can complete it in half day of 15 days.
