Rita's income is 15% less than Richa's income. By what percent is Richa's income more than Rita's income?

Let the income of Rita = $$T$$

Let the income of Richa = $$C$$

Given, Rita's income is 15% less than Richa's income

$$=$$>   $$T=\frac{85}{100}C$$

$$\therefore\ $$Required Percentage = $$\frac{C-T}{T}\times100$$

$$=\frac{C-\frac{85}{100}C}{\frac{85}{100}C}\times100$$

$$=\frac{\frac{15}{100}C}{\frac{85}{100}C}\times100$$

$$=\frac{15}{85}\times100$$

$$=\frac{300}{17}$$

$$=17\frac{11}{17}$$

Hence, the correct answer is Option D
