Text Solution

Verified by Experts

The correct Answer is:
B
If the unknown number is taken to be `x`, then three times the number is `3x` and the sum of `3x` and `11` is `32`. That is, `3x + 11 = 32`
To solve this equation, we transpose `11` to `RHS`, so that
`3x = 32 - 11` or `3x = 21`
Now, divide both sides by `3`
`x=21/3=7`
The required number is `7`.
