Let the number of males and number of females in 2018 be '60a' and '70a', respectively. So, number of males in 2019 = '60a' X 0.9 = '54a' Or, number of females in 2019 = '70a' X 1.2 = '84a' ATQ, (84a - 60a) = 48 Or, 24a = 48 So, 'a' = 2 Therefore, required number of people = (54a + 84a) = '138a' = 138 X 2 = 276
