Question

A and b can complete a piece of work in 15 days and 10 days respectively. They contracted to complete the work for rs.30,000. The share of a in the contracted money will be:/

Answer 1

the ratio of completion of work from A to B = 3:2
so the; 30,000= 3x+2x
5x =30000
x =30000 ÷5
x=6000

Answer 2

Answer:

Rs.12000

Step-by-step explanation:

A completes work in 15 days .

B completes work in 10 days.

We know that amount must be shared as the ratio of their efficiencies.  

So efficiencies of A : B= $\frac{1}{15} :\frac{1}{10}$

                                      =10:15

                                      =2:3

Sum of efficiencies =2+3=5

So A share in the total  =  $\frac{2}{5} \times 30000$

                                                 = Rs.12000

Hence  The share of a in the contracted money will be Rs.12000
