Question 83
After deducting 12% from a certain sum and then deducting 25% from the remainder, 2508 is left, then what is the initial sum?
Solution
Let initial sum = $$100x$$
After deducting 12%, sum left = $$\frac{(100-12)}{100}\times100x=88x$$
Similarly, after deducting 25%, sum left = $$\frac{75}{100}\times88x=66x$$
According to ques,
=> $$66x=2508$$
=> $$x=\frac{2508}{66}=38$$
$$\therefore$$ Initial sum = $$100\times38=3800$$
=> Ans - (D)
