Question

If x : 5 = 5 : 2, then (8 x + 9 Y) : (8 x + 2 Y) is-
A) 22:29
B) 26:61
C) 29:22
D) 61:26
​

Answer 1

We take x = 5 and Y = 2 then
8*5+9*2/8*5+2*2
=40+18/40+4
=29/22 
your answer will be 29/22

Option (C) is right

Answer 2

x:5=5:2

let x=5 and y =2

so the equation we get is

$\frac{ (8×5+9×2) }{ ( 8×5 + 2×2}$

$\frac{58}{44}$

$\frac{29}{22}$

so the ratio is 29:22
