Question

A dealer claiming to sell at cost price still
gains 25%. What weight does
does he
substitute for a kg?
(1) 900 g
(2) 800 g
(3) 750 g
(4) 850 g​

Answer 1

Answer:

(2) 800 g

Step-by-step explanation:

Initial claim CP=SP, so no profit no loss.

But still gains 25%, i.e he is giving less weight for a kg.

Let x (gms) be the weight substituted for a kg.

Then  $\frac{1000-x}{x} = \frac{25}{100}$

i.e. (1000-x) gms is his profit on each x gms substituted.

So, solving x = 800 gms
