Question

in a park, the number of plants increase by 9% over the previous year. of the number of plants now is 62130, how many many plants were there in previous year?

Answer 1

Answer:

There were 57000 plants in the previous year.

Step-by-step explanation:

Let p be the number of plants in the previous year.

Number of plants now

= p increased by 9%

= p  +  9% of p

= p  +  0.09 × p

= ( 1 + 0.09 ) × p

= 1.09 × p

We are given that the number of plants now is 62130, so

1.09 × p = 62130

=> p = 62130 / 1.09 = 57000
