Best answer
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
