Answer 1

Answer:

According to given problem,

By selling some goods at Rs. 31, a salesman loses 7% on his output. What is the percentage profit or loss, when he sells the same at Rs. 35?

Let C denotes the cost-price of the given goods.

Let S1 & S2 denote the initial & final sell-prices of the given goods.

Let PL1 denotes initial percentage loss.

Let PP2 or PL2 denote final percentage profit or percentage loss respectively.

Step-by-step explanation:

From above mentioned data we get following relations,

(1 - 7/100)*C = S1 = 31 or 0.93*C = 31 or C = 31/0.93 = 33.33 (Rs)

PP2 = 100*(S2 - C)/C = 100*(35 - 33.33)/33.33 = 5% [Ans]
