Question

Ramesh earns $₹28000$ per month. His wife Rama earns $₹36000$ per month. Find the ratio of Rama's earnings to their total earnings.

Answer 1

We have,

Money earned by Ramesh$=₹28000$

Money earned by Rama$=₹36000$

So, Total earnings of Ramesh and Rama$=28000+36000=₹64000$

$\begin{array}{lcl}\mathrm{Therefore},\mathrm{ratio}\mathrm{of}\mathrm{Rama}\text{'}\mathrm{s}\mathrm{earnings}\mathrm{to}\mathrm{their}\mathrm{total}\mathrm{earnings}& =& \frac{\mathrm{Earning}\mathrm{of}\mathrm{Rama}}{\mathrm{Total}\mathrm{earnings}}\\ & =& \frac{36000}{64000}\\ & & \mathrm{Dividing}\mathrm{numerator}\mathrm{and}\mathrm{denominator}\mathrm{by}4000\\ & =& \frac{9}{16}\\ & =& 9:16\end{array}$

Hence, required ratio is $9:16$
