Question

Mohan think a number. If he takes away 7frim 5/2of the number, the result is 11/2. What is the number​

Answer 1

He has probably lost it or acting weird

Answer 2

Let the no. Mohan thought of be x.

He takes aways 7 from 5/2 of the no.

This means (5/2)x-7

The result is 11/2

So,

(5/2)x-7=11/2

(5/2)x=11/2+7

(5/2)x=(11+14)/2

(5/2)x=25/2

x=(25/2) x (5/2)

x=5

Therefore the no. Mohan thought of was 5.

Hope this helps you.
