Question

a shopkeeper marks his good to gain 35%.if he allows 10% discount for cash.find the gain% on a cash transaction​

Answer 1

Answer:

According to the given problem,

(i) A shopkeeper marks his goods at 35% above the cost price and allows a discount of 10%.

(ii) Let PP denotes his profit percentage.

(iii) Let C, M & S denote respectively the cost-price, marked-price & the sell-price of the goods.

From (i) & (iii) we get following relations,

M = (1 + 35/100)*C …… (1a)

S = (1 - 10/100)*M …… (1b)

From (1a) & (1b) we get,

S = (1 - 10/100)*(1 + 35/100)*C

or S = 0.90*1.35*C = 1.215*C

or S = (1 + 21.5/100)*C …… (1c)

Therefore from (ii) & (1c) it is evident that,

PP = 21.5% [Ans]
