1. Answer:

   12

   Step-by-step explanation:

   Let’s divide the % into two parts I.e,

   60%=50%+(3×10%)

   Now, 50% of the number 20 should be calculated

   Just divide the number by 2 to get 50% of any number..

   20÷2=10

   10% of 20 :

   Place the decimal point after the units place of a number to get 10% I.e

   2.0

   Now 10 +(2×1)=10+2=12

   80% of 20 is 12.

   Hope it helps you
