let the fare of ticket from A to B be x and the fare of ticket from A to C be y .It is said that the cost of 2 tickets from A to B and three tickets from A to C is ₹77 and the cost of 3 tickets from A to B and 2 tickets from A to C is ₹73 . => we get 2x+3y= 77...(1)
And 3x+2y= 73...(2) Multiply equation (1) by 3 and equation(2) by 2, we get then 6x+9y =231...(1) And 6x+4y=146...(2) Now subtract equation(2) from (1), we get 6x+9y-(6x+4y)=231-146=85=> 5y=85=> y=85/5 =17. Now substitute y=17 in equation(1), we get 6x+9(17)=231=> 6x=231-153=78=>x=13 So B is the correct option.Hope it helps you...
