Question

At ABC Itd, the average age of employees is 36. Average age of male employees is 38 and that of females is 32. Find the ratio of female to male in the company. (a) 1.3 (b) 2:1 (C) 1.2 (d) 3:1 ​

Answer 1

Step-by-step explanation:

from the problem it is given that;

combined AM= 36 YRS (Combined AM)

AM of male employees = 38 (AM of 1st obv)

AM of female employees = 32 (AM of 2 obv.)

We know that

Combined AM = {(AM of 1 obv.)×(Tot. no of 1st obv)} + {(AM of 2 obv.)×(Tot. no of 2nd obv)} ÷ (Tot. no of 1st obv) + (Tot. no of 2nd obv)

By substituting the given values in above formula

36 = 38×n(1) + 32×n(2) ÷ n(1) + n(2)

n(2): n(1) = 1:2 { option c is the required answer}
