Question

A dishonest fruit vendor professes to sell his goods at a profit of 10% but he uses a weight of 800 g for the kg weight. Find his gain%

Answer 1

profit=10%
weight=800KG
                       =[10/100]x800KG
                       =10x800
                       =8000kg
                       

Answer 2

Dear Student,

● Answer -

Fruit seller's gain is 37.5 %.

● Explaination -

Given that fruit-seller uses a weight of 800 g for the kg weight.

So this fruit seller sells his goods at -

Propessed SP = CP × (100+10) %

Propessed SP = CP × 110 %

But original selling price per kg is -

Original SP = Professed SP × 1000/800

Original SP = CP × 110 % × 1000/800

Original SP = CP × 137.5 %

Hence, gain to the fruit seller is 137.5 - 100 = 37.5 %.

Thanks dear. Hope this helps you...
