A number is first increased by 20% and then reduced by 15%. If the final value is 2040, then what is the initial value of the number?
Solution
Let the initial number be x.
$$\frac{120}{100} \times \frac{85}{100} x = 2040$$
x = $$\frac{2040 \times 100 \times 100}{120 \times 85}$$ = 2000
So , the answer would be option c)2000.
