Question

If the ratio between 8 and 11 is the same as the ratio of 2x - y to x + 2y. Find the value of `(7x)/(9y)`

Solution

`(2x - y)/(x + 2y) = 8/11`

22x - 11y = 8x + 16y

Given 14x =27y

`x/y = 27/17`

`(7x)/(9y) = (7 xx 27)/(9 xx 114) = 3/2`

  Is there an error in this question or solution?
