Question

if x:y=5:7 then find (3x+4y) : (x+2y)

Answer 1

It is given that

x : y = 5 : 7

Let x = 5a and y = 7a


We have to find

(3x + 4y) : (x + 2y)

Substitute the value of x and y

=> {3(5a) + 4(7a)} : {5a + 2(7a)}

=> (15a + 28a) : ( 5a + 14a)

=> 43a : 19a

So ratio = 43a/19a

=> ratio = 43 : 19


Your answer is 43 : 19
