Answer 1

Given:-

• Anuj thinks of a number
• If he takes away 7 from 5/2 of the number the result is 23.

To Find:-

• Find the number

Explaination:-

Let the number be 'x'.

$\implies \sf {x \times \frac{5}{2} -7=23}$

$\implies \sf {x \times \frac{5}{2} =23+7}$

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

$\implies \sf{x \times 5 = 30 \times 2}$

$\implies \sf{x \times 5 = 60}$

$\implies \sf{x = \frac{60}{5} }$

$\implies \sf{x = 12 }$

So, 12 is the number.

Answer 2

Question:-

Anuj thinks of a number.If he takes away 7 from 5/2 of the number the result is 23. Find the number....

Solution:-

The number is 12

Step-by-step:-

Let the number be x

Let the number be 5/2 of the number

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

So, 5/2x -7 =23

Then we have to reciprocate it as 7+23=30

x = 2/5 × 30

x = 60

x = 60/5

x = 12

Therefore ; the number is 12.
