Answer 2

If 8% of a number is 72 then 10% of that no is 90

Step-by-step explanation:

Let the number be x

Given 8% of a number is 72

so 8% of x=72

or 8x $=72\times100$

or 8x $=7200$

or x $=\frac{7200}{8}$

or x $=900$

10% of the number = 10% of x

                             $=\frac{10}{100} \times900$

                              $=10\times9$

                              $=90$

so 10% of that number is 90
