Question

Anita earns $Rs.8,000$ a month and Sunita earns $Rs.20,000$ a month, then find the ratio between Sunita's income to their total income.

Answer 1

Anita income per month $=Rs.8,000$

Sunita income per month $=Rs.20,000$

Their total income $=8000+20,000$

$=28,000$

Ratio of Sunita income to their total income = $\frac{20000}{28000}$

$=\frac{5}{7}$

$=5:7$

Hence, the required ratio is $5:7$.
