Question
A seller marked an article 60% above its cost price and
sold it after allowing 25% discount. If he made a profit of Rs. 45, then find the difference between selling price and marked price of the article.Solution
Let the cost price of the article be Rs. ‘2x’
So, marked price of the article = 2x × 1.6 = Rs. ‘3.2x’
Selling price of the article = 3.2x × 0.75 = Rs. ‘2.4x’
Profit = 2.4x – 2x = Rs. ‘0.4x’
ATQ;
0.4x = 45
Or, x = 112.5
So, marked price of the article = 112.5 × 3.2 = Rs. 360
Selling price of the article = 112.5 × 2.4 = Rs. 270
Required difference = 360 – 270 = Rs. 90
If + means ÷, ÷means –, –means ×, × means +, then 200 + 10 ÷ 10 – 10 × 5 = ?
