Question 83
After deducting 60% from a certain number and then deducting 15% from the remainder, 1428 is left. What was the initial number?
Solution
$$\frac{100-15}{100}\times \frac{100-60}{100}\times X = 1428$$
$$\frac{85}{100}\times \frac{40}{100}\times X = 1428$$
$$\Rightarrow X = 4200$$
so the answer is option A.
