Answer 2

Answer:

Share of A's is Rs.250.            

Step-by-step explanation:

Given : A can do a work in 12 days while b can do it in 15 days. They undertake to complete it together for Rs. 450.

To find : What will be the share of a in this amount of money?

Solution :

A can do a work in 12 days.

Work done by A is 1 day = $\frac{1}{12}$

B can do a work in 15 days.

Work done by B is 1 day = $\frac{1}{15}$

The ratio of their wages is

$\frac{1}{12} :\frac{1}{15}$

$15:12$

$5:4$

So, Share of A is $=\frac{5}{5+4}\times 450$

$=\frac{5}{9}\times 450$

$=250$

Share of B is 450-250=Rs.200

Therefore, Share of A's is Rs.250.
