Answer» Correct Answer - Option 2 : Rs. 8900 Given: Spent on repairs = Rs. 1100 P’s profit = 20% Q’s loss = 10% R’s profit = 10% R’s S.P = Rs. 11880 Calculations: Let P’s C.P after repairing be x. ∴ According to the question, ⇒ 110% of 90% of 120% of x = 11880 ⇒ 110/100 × 90/100 × 120/100 × x = 11880 ⇒ x = (11880 × 10 × 10 × 10)/(11 × 9 × 12) ⇒ x = 10000 ∴ P purchased it for Rs. (10000 – 1100) = Rs. 8900 P bought the old TV for Rs. 8900. |
