Detailed Solution

Concept- One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.
First, we'll calculate 60% of 80 and then subtract the result from 80.
To calculate 60% of 80
  = 60100×80       =4800100    =48          Now, subtract the solution from 80 i.e.
=80-48
=32
The required no. which is 60% less than 80 is   32.
Hence, the correct option is 3) 32
