Question

A washing machine is marked at $7500Rs$. The dealer allows successive discounts of $8$%, $5$% and $2$% on it. What is the net selling price (rounded to nearest integer)?

Answer 1

Marked price = Rs. $7500$

First discount = $8$% of $7500$ = Rs$(\frac{8}{100}\times 7500)$ = Rs. $600$

Net price after 1st discount = Rs$(7500-600)$ = Rs. $6900$

Second discount = $5$% of Rs.$6900$ = $Rs(\frac{5}{100}\times 6900)$ = Rs. $345$

Net price after 2nd discount = Rs$(6900-345)$ = Rs.$6555$

Third discount = $2$% of $6555$ = Rs$(\frac{2}{100}\times 6555)$ = Rs. $131.1$

Net selling price = Rs$(6555-131.1)$ = $6423.90$

The net selling price of the washing machine is $6423.90$.
