Question

In a certain town there were 243 robberies last year. This year the number of robberies has gone down 28%. How many robberies were there this year, to the nearest whole number?

Answer 1

Answer: 175 robberies

Step-by-step explanation:

Robberies last year= 243

Robberies has reduced by 28% which means there are (100-28)% = 72% robberies this year.

Number of robberies this year= 72% of 243 = 72/100 × 243 = 174.96 = 175.

There are 175 robberies this year

Answer 2

Answer: 175

Step-by-step explanation:

The original number of robberies = 243

It has been reduced by 28% , to find the present number of robberies , all we need do is to find 72% of 243. That is

72% x 243

= 0.72 x 243

= 174.96

Therefore , the number of robberies this year to the nearest whole number will be 175
