Answer» Hey friend, here is your answer - Let the NUMBER of students in the class be x Number of boys in the class = 40/100 * x = 2/5x Number of girls in the class = x - 2/5x = 3/5x ATQ, 2/5x - 4 = 4/7 * (3/5x - 4) ⇒ 2/5x - 4 = 12/35x - 16/7 ⇒ 2/5x - 12/35x = -16/7 + 4 ⇒ 2/35x = 12/7 ⇒ x = 12/7 * 2 * 1/35 ⇒ x = 24/245 This is the CORRECT answer according to the DATA given in the question But now even I am confused how there can be people in FRACTION.
