Correct Answer - Option 2 : Rs.450

Given:

Let initial investment of Ramu be Rs.a.

⇒ Total investment of Raju = 250 × 7 + 400 × 5 = Rs.3750

⇒ Total investment pf Ramu = a × 7 + (a - 150) × 5 = Rs.(12a - 750)

Total profit shares of Raju and Ramu = Rs.2800

The difference between the profit shares = 300

Solving,

⇒ The profit share of Raju = Rs.1250

⇒ The profit share of Ramu = Rs.1550

Then,

⇒ 3750 : (12a - 750) = 1250 : 1550

⇒ a = 450

∴ Initial investment of Ramu is Rs.450.
