Correct Answer - Option 3 : Rs. 40,36,500
Given:
Total employees = 690
Average salary = Rs. 17100
Graduate's salary = 250% of nongraduate's salary
Nongraduate employees = 130% of graduate employees
Formula used:
Average = sum of observations/total number of observations
Calculation:
Let the number of graduate employees be x
So, nongraduate employees = 1.3x
∴ 2.3x = 690
⇒ x = 300 and 1.3 x = 390
Now, let the salary of a nongraduate be Rs. y
Graduate's salary = 2.5 y
A.T.Q
(2.5y × 300) + (390y) = 690 × 17100
⇒ 1140 y = 690 × 17100
⇒ y = Rs. 10350
∴ Required salary = 390 × 10350 = Rs. 4036500
∴ The answer is Rs. 4036500
