Answer» Correct Answer - Option 1 : 25%

Calculations:

Let us say that initially there were 100 commuters.

The distribution of different modes would be a below.

⇒ Car in Jan 2019 = 30% of 100 = 30

⇒ Bus in Jan 2019 = 20% of 100 = 20

⇒ Two Wheelers in Jan 2019 = 10% of 100 = 10

⇒ Metro in Jan 2019 = 40% of 100 = 40

Now, in Feb the total commuters have increased by 50%,

so total commuters in Feb 2019 = 100 + 50% of 100 = 150

⇒ Car in Feb 2019 = 30 + 33.33% of 30 = 40

⇒ Bus in Feb 2019 = 20 + 100% of 20 = 40

⇒ Two Wheelers in Feb 2019 = 10 + 100% of 10 = 20

⇒ Metro in Feb 2019 = 150 - (40 + 40 + 20) = 50

Change in metro = 50 - 40 = 10 

Percentage change in metro = (10/40) × 100 = 25% 

∴ Percentage change in metro is 25%.
