Question

A person buys 18 local tickets for Rs. 110. Each first class ticket costs Rs. 10 and each second class ticket costs Rs. 3. What will another lot of 18 tickets, in which the number of first class and second class tickets are interchanged, cost?

• A. Rs. 112
• B. Rs. 118
• C. Rs. 121
• D. Rs. 124

Hint:

First solve for the original number of first and second class tickets, then swap the two counts and recompute the total cost.

Answer 1

The Correct Option is D

x=8,y=10 (first class, second class). New cost - old cost = 7(y-x)=7(2)=14. New cost=110+14=124.

Final Answer: Rs. 124, option (4).
