Question

What is the final amount if 1443 is increased by 9% followed by a 6% decrease? Give your answer to 2DP.

Answer 1

The final reduced amount is 1234.33.

Explanation:

Here, the initial amount is given to be = 1443

Now, Case A: The amount gets decreased by 9%

Calculating 9% of the given amount 1443, we get:

9 % of 1443 =
`(9)/(100)  * 1443 = 129.87`

or, the decrease in the amount of 1443 = 129. 87

So, the Reduced amount = Actual Amount - Reduction Amount

= 1443 - 129. 87 = 1313.12

or, the reduced amount is 1313.12

Now, Case B: The amount gets further decreased by 6%

Calculating 6% of the given amount 1313.12, we get:

6 % of 1313.12 =
`(6)/(100)  * 1313.12 = 78.7872`

or, the decrease in the amount of 1313.12 = 78.7872

So, the final Reduced amount = Amount - Reduction Amount

= 1313.12 - 78.7872 = 1234.33

Hence, the final reduced amount is 1234.33.
