Question

Sandra saves 8% of her salary for retirement. This year her salary was 3,000 more then in the previous year , and she saved 3,600. What was her salary in the previous year

Answer 1

42000

Explanation:

Given that:

Amount of money saved by Sandra for retirement = 8%

Salary this year is 3,000 more than that in the previous year.

Total amount of money saved = 3,600

To find:

The salary in the previous year = ?

Let the salary in the previous year =
`x`

As per question statement, we can write the equation as:

`(x+3000)* 8\% = 3600\\\Rightarrow (x+3000)* (8)/(100) = 3600\\\Rightarrow (x+3000)* 8 = 360000\\\Rightarrow 8x+24000 = 360000\\\Rightarrow 8x= 360000 - 24000 \\\Rightarrow 8x = 336000\\\Rightarrow x = 42000`

Therefore, the salary in the previous year was 42000.
