Question

If the compound ratio of 3:4 and 5:3 is 30:x, then find the value of 'X.​

Answer 1

Step-by-step explanation:

compound ratio = 30:x

3/4×5/3=30/x

15/12 =30/x

15x = 12×30

x= 12×30/15

x= 24

Answer 2

Answer:

The correct answer is - 24.

Step-by-step explanation:

Compound ratio is the ration which is get by the multiplication of two or more ratio this is why it is called compound ratio. Compound ratio can be find by the-

ab:cd, where ab is the product of two nemerator and cd is the product of denominator of two ratios which are a:c and b:d.

So, the compound ratio would be:

$\frac{3}{4}  \times \frac{5}{3} =\frac{30}{x}$

$15x = 12\times 30$

$x= \frac{12\times30}{15} x= 24$

Thus, the correct answer is - 24
