Correct Answer: Rs. 265
Solution : Let per day income of a boy, woman, and man be $x, x+10,$ and $x+20,$ respectively. According to the question, $\frac{\text{Total income of (7 Men + 11 Women + 2 Boys)}}{20} = 257.50$ Putting the values, we get: $7(x+20)+11(x+10)+2x = 257.50×20$ $⇒7x+140+11x+110+2x = 5150$ $⇒20x = 5150 - 250$ $⇒x = \frac{4900}{20}$ $\therefore x= 245$ $\therefore$ Average daily income of a man $ = x + 20 = 245 + 20 = 265$ Hence, the correct answer is Rs. 265.
