Question
If 25 men earn Rs 1000 in 10 days, how much will 15 men earn in 15 days?
Solution
\[\text{ Earnings of 25 men in 10 days } = Rs . 1000\]
\[ \therefore \text{ Earnings of 25 men in 1 day }= Rs . \frac{1000}{10} = Rs . 100\]
\[ \therefore \text{ Earning of 1 man in 1 day } = Rs . \frac{100}{25} = Rs . 4\]
\[ \therefore \text{ Earnings of 1 men in 15 days } = Rs . \left( 15 \times 4 \right) = Rs . 60\]
\[ \therefore \text{ Earnings of 15 men in 15 days } = Rs . \left( 60 \times 15 \right)\]
\[ = Rs . 900\]
