Question

26. If 25% of a number p is 19, what is 15% of p?

Answer 1

Given:

25% of p is 19.

`\begin{gathered} (25)/(100)* p=19 \\ p=19*(100)/(25) \\ p=19*4 \\ p=76 \end{gathered}`

The expression to calculate the 15% of p is,

`(15)/(100)* p`

Substitute value of p=76 in the above expression.

`\begin{gathered} (15)/(100)*76=(3)/(20)*76 \\ =(228)/(20) \\ =11.4 \end{gathered}`

Thus, 15% of p is 11.4.
