Question

IFx:y=2:3,y:z=6:7,fimdx:yz?

Answer 1

x : y = 2 : 3 ------- eq. 1

y: z = 6 : 7 ------- eq. 2

Now multiply 6 in eq. 1 and 3 in eq. 2

x : y = 12 : 18

y : z = 18 : 21

So , x is 12 , y is 18 , z is 21

So, x : y : z = 12 : 18 : 21

We can also divide them by 3

So, x : y : z = 4 : 6 : 7

Hope it helps...
