The average monthly salary of all the employees in an industry is ₹ 12,000. The average salary of male employees is ₹ 15,000 and that of female employees is ₹ 8,000. What is the ratio of male employees to female employees ?
-
- 5 : 2
- 3 : 4
- 4 : 3
- 2 : 5
- 5 : 2
Correct Option: C
Let Male employees = p
Female employees = q
∴ (p + q) 12000 = p × 15000 + q × 8000
⇒ (p + q) × 12 = 15p + 8q
⇒ 12p + 12q = 15p + 8q
⇒ 3p = 4q
| ⇒ | = | ||
| q | 3 |
⇒ p : q = 4 : 3
