(c) Rs. 1800

Since the wage distribution will follow the work distribution ratio, we have:

Work done by A in 1 day $=\frac{1}{10}$
Work done by B in 1 day $=\frac{1}{15}$

Net work done by (A+B) in 1 day $=\frac{1}{10}+\frac{1}{15}=\frac{5}{30}=\frac{1}{6}$

i.e., (A+B) will take 6 days to complete the work.

A's share of work in a day = $\frac{1}{10}÷\frac{1}{6}=\frac{1}{10}×\frac{6}{1}=\frac{6}{10}=\frac{3}{5}$

∴ A's wage =

#### Question 7:

(c) Rs. 1800

Since the wage distribution will follow the work distribution ratio, we have:

Work done by A in 1 day $=\frac{1}{10}$
Work done by B in 1 day $=\frac{1}{15}$

Net work done by (A+B) in 1 day $=\frac{1}{10}+\frac{1}{15}=\frac{5}{30}=\frac{1}{6}$

i.e., (A+B) will take 6 days to complete the work.

A's share of work in a day = $\frac{1}{10}÷\frac{1}{6}=\frac{1}{10}×\frac{6}{1}=\frac{6}{10}=\frac{3}{5}$

∴ A's wage =
