Show answer & explanation

Correct answer: D

Explanation

The correct answer in option 4 i.e. 3:2

Percent increase in production of medicines of the year 2011 = (60 - 40)/40 × 100 = 20/40 × 100 = 50%

Percent increase in production of medicines of the year 2015 = (80 - 60)/60 × 100 = 20/60 × 100 = 100/3%

The ratio will be 50% : 100/3%

⇒ 1 : 2/3

⇒ 3 : 2
