Correct option is A
Given:
Purchasing Price of TV = Rs. 4,600
S.P of TV = Rs. 5,406
Profit percentage = 6%
Formula used:
Profit = (SP) - (CP)
Profit% = (Profit/CP) × 100
Final CP = Purchasing Price + Repair Cost
Solution:
=> Profit = (Profit% × CP) / 100
=> 5,406 - CP = (6 × CP) / 100
=> 540,600 = 6 × CP + 100 × CP
=> 540,600 = 106 × CP
=> CP = 540,600 / 106
=> CP = 5,100
=> CP = Purchasing price + Repair Cost
=> 5,100 = 4,600 + Repair Cost
=> Repair Cost = 5,100 - 4,600
=> Repair Cost = Rs. 500
Hence, option (a) is correct answer.
Rupert has spent Rs. 500 on the repairing of TV.
