Two bus tickets from city A to B and three tickets from city A to C cost Rs. 77 but three tickets from city A to B and two tickets from city A to C cost Rs. 73. What are the fares for cities B and C from A ?  Choose the correct choice from the following answers:
A) Rs. 13, Rs. 19	B) Rs. 13, Rs. 17	C) Rs. 13, Rs. 12	D) Rs. 13, Rs. 11	E) Rs. 13, Rs. 10
Explanation:   Let Rs. x be the fare of city B from city A and Rs. y be the fare of city C from city A.   Then, 2x + 3y = 77 ...(i) and   3x + 2y = 73 ...(ii)   Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y = 17.   Putting y = 17 in (i), we get: x = 13.   Answer: B) Rs. 13, Rs. 17
