Question

A solution is obtained by mixing three solutions X, Y and Z such that the ratio X : Y is 3 : 2 and the ratio Y : Z is 5 : 7. Find the amount of solution Z in 19.5 litres of the solution​

Answer 1

Answer:

We have, x:y=5:2 and y:z=3:2,

⇒

y

x

=

2

5

and

z

y

=

2

3

Now multiply both

⇒

y

x

⋅

z

y

=

2

5

⋅

2

3

⇒

z

x

=

4

15

, simplify

∴x:z=15:4
