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

Step-by-step 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
