Correct Answer - Option 3 : Raju's gain Rs. 3,150
Given:
Cost price of car = Rs.150000
Formula:
Profit = SP - CP
SP = CP × (100 + Profit%)/100
Calculation:
SP for Raju = 150000 × 105/100 = Rs.157500
CP for Montoo = SP for Raju
Then,
CP for Raju = 157500 × 98/100 = Rs.154350
Total profit Raju had = 157500 - 154350 = Rs.3150
∴ Raju's profit in entire transaction is Rs.3150.
