Verbal Reasoning - Arithmetic Reasoning - Discussion

I cant get this, please explain.

I am truly lost, please help. Where does (i) and (ii) fit in?

I cant get this, please explain (1) and (ii).

2x + 3y = 77 multiply this line with 3 so it becomes
6x + 9y = 231-----------(i)

3x + 2y = 73 multiply this line with 2 so it becomes
6x + 4y = 146 -------------(ii)

now solve both the equestion (i) and (ii)
6x + 9y = 231
6x + 4y = 146
----------------
ox + 5y = 85

y = 85/5 = 17

in the same way do for X ..

New method

3 tickets A to B
2 tickets A to c
that's 77/5 = 15.4

3 tickets A to B
2 tickets A to C
that's 73/5 = 14.6

so 15.4+14.6 = 30
Ans: 13 + 17 = 30 --- (B)

It is wrong antony. In options 17 and 13 is also there. So your method is wrong.

Vijay method is correct.

Vijay why did you first multiply by 3 and then by 2 why not the reverse... How would you manage the negative output when you multiply first line by 2 and second line by 3

i.e 4x + 6y
9x + 6x
-------------
Minus = 5x ?

Don't know if I made sense with my question.

Let, A to B fare as X and A to C as Y

(2x + 3y = 77)X 3 ---------------(1 line)
(3x + 2y = 73)X 2 ---------------(2 line)
now, after multiplications, we get

6x + 9y = 231---------------(1 line)
6x + 4y = 146---------------(2 line)

now, after change the signs and solve the equation, we will get

6x + 9y = 231
-6x - 4y =-146
----------------
ox + 5y = 85

OR,5y = 85

Y= 85/5
OR, Y= 17
NOW, put the value of y in any line, for Eg. in first line, as under:-

2x+3y=77------(1 line)
2x+3(17)=77
2x+51=77
OR, 2x=77-51
2x=26
x=26/2
x=13
SO,
13 and 17 is the answer

@Vijay

You are method is so good. easy way to understand..in Vijay method if any x,y coefficient should made equal to the values. Because we find x,y values..thats why he multiple 3 with first equation and 2 with second equation.
