Question

a trader weights 900 gram for 1 kg and earn a profit of 8% what is his real profit ?​

Answer 1

Answer:

20%

Step-by-step explanation:

Solution :

The trader professes to sell his goods at a profit of 8%.

Selling Price = (100 + 8)% = 108% of Cost Price

or SP = 1.08CP

But, when he uses weights that measure only 900 grams while he claims to measure 1 kg.

CP of 900 gms = 0.90CP

So, he is selling goods worth 0.90CP at 1.08CP

He makes a profit of 0.18 CP on his cost of 0.9 CP

Therefore, The profit percentage =>

(1.08 - 0.9)/0.9 * 100

=> 0.2 * 100 = 20%
