Question

Maria studied the traffic trends in India. She found that the number of cars on the road increases by 10% each year. If there were 80 million cars in year 1 of her study, how many more cars were on the road in year 3 compared to year 2?

Answer 1

Answer: 8,800,000

Explanation:

First year recorded number of cars on the roads = 80, 000,000

Increase rate = 10%

In the second year , the number of cars recorded = 10% of 80,000,000

= 10/100 x 80,000,000

= 8,000,000

= 80,000,000 + 8,000,000

= 88,000,000

In the third year, the number of cars recorded = 10% of 88,000,000

= 10/100 x 88,000,000

= 8,800,000

= 88,000,000 + 8,800,000

= 96,800,000.

The number of cars we had more in the third years compared to year two will be

= 96,800,000 - 88,000,000

= 8,800,000
