Question

Anwar thinks of a number. If he is taking away 7 from 5/2 of the number,the result is 23. What is the number?

Answer 1

let the no. is x
(X×5/2)-7=23
X×5/2=23+7
X×5/2=30
X×5=30×2
X=60/5
X=12
12 is the number

Answer 2

Answer:

12

Step-by-step explanation:

Let the number be x

5/2 of the number=$\frac{5}{2}x$

Now Anwar  is taking away 7 from $\frac{5}{2}x$ =  $\frac{5}{2}x-7$

We are given that If he is taking away 7 from 5/2 of the number,the result is 23.

So,  $\frac{5}{2}x-7=23$

$\frac{5}{2}x=30$

$x=30 \times \frac{2}{5}$

$x=12$

Hence The number is 12
