A) Rs. 13 and Rs. 17 B) Rs. 17 and Rs. 19
C) Rs. 23 and Rs. 17 D) Rs. 13 and Rs. 19
 
Answer & Explanation Answer: A) Rs. 13 and Rs. 17

Explanation:

If fares for cities L and M from K are x and y respectively, then

2x + 3y = 77 or 6x + 9y = 231...(1)
3x + 2y = 73 or 6x + 4y = 146...(2)

subtracting 2 from 1, we get

5y = 85

y = Rs. 17 => x = Rs. 13
