| Ramesh earns Rs. 28000 per month. His wife Rama earns Rs. 36000 per month. Find the ratio of |
| (a) Ramesh's earnings to their total earnings. |
| (b) Rama's earnings to their total earnings |
Answer:
Given, Ramesh earns per month = Rs. 28000
and Rama earns per month = Rs. 36000
\[\therefore \] Total earnings = (Ramesh earns per month + Rama earns per month)
\[=Rs.\text{ (}28000+36000)=Rs.\text{ }64000\]
(a) Ratio of Ramesh?s earnings to their total earnings
= Ramesh?s earnings : Total earnings
\[=28000:64000\]
\[=28:64\] [dividing by 1000 in both ratios]
\[=7:16\][dividing by 4 in both ratios]
Hence, the ratio of Ramesh?s earnings to total earnings is \[7:16\].
(b) Rama?s earning?s to their total earnings
= Rama?s earnings : Total earnings
\[=36000:64000\]
\[=36:64\][dividing by 1000 in both ratios]
\[=9:16\][dividing by 4 in both ratios]
Hence, the ratio of Rams?s earnings to their total earnings is \[9:16\].
