Correct Answer: 57 and 38
Solution : Let one of them get $x$ marks. Then the other one gets ($x + 19)$ marks. According to the question, $x + 19 = (x + x + 19) × \frac{60}{100}$ ⇒ $x + 19 = (2x+ 19) × \frac{3}{5}$ ⇒ $5(x + 19) = 3(2x + 19)$ ⇒ $5x + 95 = 6x + 57$ $\therefore x = 38$ So, one got 38 and the other got (38 + 19) = 57 Hence, the correct answer is 57 and 38.
