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%…

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)
