Ques:- A is thrice as efficient as B and is, therefore, able to finish a piece of work 10 days earlier than B. In how many days A and B will finish it together?
Recent Answer : Added by Abhi Chatterjee On 2022-01-08 16:05:10:
Let n be the number of days it takes A and B, working together, to finish. And we know B=A+10 and B=3A, so:
3A=A+10
2A=10
A=5
Then B=15
So:
1/A + 1/B=1/n where n is the total amount of days. So:
1/5 + 1/15=1/n
3n+n=15
n=15/4 days

Recent Answer : Added by Admin On 2022-09-29 17:11:51:
A & B one day work= 1/18 + 1/30= 8/90
