Question

If 66:72 is proportional to x:96 then find value of x

Answer 1

Answer:

88 because it is proportional

Answer 2

Answer:

The value of x = 88

Explanation:

To find whether the ratios are propotional or not, we have to find the product of means and extremes.

Here, the means are 72 and x whereas extremes are 66 and 96. If we find the product of extremes and we get 6336.

Now, we have only one known means i.e. 72. The x is also a means. So, as there is only one means, we have to divide the product of extremes by the means i.e. 6336/72=88.

The value of x = 88
