Question
"A seller marked an item 'a'%
above its cost price and sold it after giving two consecutive discounts of 20% and 25%. Determine the value of ‘a’ if the shopkeeper incurred a 7% loss in this transaction."Solution
ATQ, Let the cost price of the item be Rs. 100 Marked price of the item = 100 x {(100 + a)/100} = Rs. (100 + a) Selling price of the item = (100 + a) 0.80 x 0.75 = (100 x 0.93) 60 + 0.6a = 93 0.6a = 33, a = 55 So, the value of 'a' = 55%
