Answer 2

Answer:

Option 3 is the answer.

Step-by-step explanation:

2/5 means 50 % is divided into 5 equal parts and two are selected from them.

i.e. ( 2/5 ) × 50 = 20%.

( NOTE : - If we make 5 equal parts of 50 then 1 part = 10. Therefore two parts = 10 % +10 % = 20 % )

So similarly , make 4 equal parts of 50 % and select any 3 parts from 4 equal parts.

i.e. ( 3/4 ) × 50 = 12.5 ×3 = 37.5

( NOTE : - If we make 4 equal parts of 50 then 1 part = 12.5 . Therefore, selecting 3 parts = 12.5 %+12.5 % +12.5 % = 37.5 % )
