Question 138

Prerna decided to donate 15% of her salary to an orphanage. On the day of donation she changed her mind and donated Rs. 1,896 which was 80% of what she had decided earlier. How much is Prerna's salary?

Solution

Let Prerna's salary = $$Rs.100x$$

Amount which Prerna decided to donate = $$\frac{15}{100} \times 100x=Rs.15x$$

Amount which she actually donated = Rs. 1896

According to ques,

=> $$\frac{80}{100} \times 15x=1896$$

=> $$\frac{4}{5} \times 15x=1896$$

=> $$12x=1896$$

=> $$x=\frac{1896}{12}=158$$

$$\therefore$$ Prerna's salary = $$100 \times 158=Rs.$$ $$15,800$$

=> Ans - (C)
