A and B decide to travel from place X to place Y by bus. A has Rs. 10 with him and he finds that it is 80% of the bus fare for two persons. B finds that he has Rs. 3 with him and hands it over to A. In this context, which one of the following statements is correct ?
- A.Now the money A has just enough to buy two tickers.
- B.A still needs Rs. 2 for buying the tickets.
- C.After buying the two tickets A will be left with 50 paise.
- D.The money A now has is still not sufficient to buy two tickets.
▶ Answer & Explanation
Correct answer: C. After buying the two tickets A will be left with 50 paise.
If Rs. 10 represents 80% of the fare for two, then the total fare for two is Rs. 10 / 0.80 = Rs. 12.50. When B gives Rs. 3 to A, A now has Rs. 10 + Rs. 3 = Rs. 13. After purchasing tickets costing Rs. 12.50, A will have Rs. 13 - Rs. 12.50 = Rs. 0.50 remaining.
