(b) Rama's earning to their total earning.
[4 marks]

Answer 1

Given, Ramesh earns = ₹28,000 per month
His wife Rama earns = ₹36,000 per month
Total earning = Ramesh's earning + Rama's earning

= ₹(28,000 + 36,000) = ₹64,000 per month
(a) Ratio of Ramesh's earning to their total earning = $\frac{₹28000}{₹64000}$ (1 mark)

= $\frac{7}{16}=7:16$
