Question

a mobile phone was marked at 35% above the cost price and a discount of 20% was given on the marked price find the profit it % or loss % made by the shopkeeper

Answer 1

Let the cost price be ₹100
then,
marked price = 100 + 35% of 100
=>₹135

now,
discount % = 20%
so, discount allowed,
=>20/100 ×135 = ₹23

so,
selling price = 135-23
=>₹112

profit = 112-100 =₹12

therefore, percent profit,
12/100 *100 = 12%

hope it helps u...
if yes, mark brainliest...
have a great day ahead....
