A fruit seller professes to sell his fruits at cost price, but still gains 25\% on his outlay. What weight does he substitute for a kilogram?
(a)800 gm
(b)850 gm
(c)890 gm
(d)900 gm
Answer
Explanation
Let error $=x \mathrm{gms}$. Then, $\frac{x}{1000-x} \times 100=25 \Leftrightarrow \frac{100 x}{1000-x}=25$ $$\Leftrightarrow 100 x=25000-25 x \Leftrightarrow 125 x=25000$$ $\Leftrightarrow x=200$. $$\text { ∴ Weight used }=(1000-200) \mathrm{gms}=800 \mathrm{gms} .$$
