When 20% of a number is added to 36 then the resultant number is 200% of the actual number. Then find 40% of actual number.   1. 102. 83. 124. 6

Answer» Correct Answer - Option 2 : 8

Calculations:

Let the actual number be x 

According to the question

⇒ 20% of x + 36 = 200% of x 

⇒ (20/100) × x + 36 = (200/100) × x 

⇒ x/5 + 36 = 2x 

⇒ 36 = 2x – x/5

⇒ 9x/5 = 36 

⇒ x = 20 

40% of x

⇒ (40/100) × 20 = 8 

∴ 40% of actual number is 8
