Time and Work Practice Test 3 with solutions

Question : 14 of 40

Marks: +1, -0

A alone can finish a work in

7 1/3

days, while B alone can finish the same work in

3 1/{12}

days. If they finished it working together, then find the total share of B, out of the total wages of Rs 1,250.

Solution:

Ratio of work done by A and B =

7 1/3 : 3 1/{12}

{22}/3 : {37}/{12}

= 88 : 37
So, the ratio of time taken by A and B = 37 : 88
So, B’s share =

{88}/{125} × 1250

= Rs 880
