JAMIA 2026 — Reasoning PYQ

JAMIA | Reasoning | 2026

A dishonest dealer uses a false weight of $800 g$ instead of $1 kg$ and claims to sell at cost price. What is his profit percentage?

Choose the correct answer:

Explanation

Method 1: Using the Shortcut Formula

For problems where a shopkeeper sells goods at the cost price but uses a false weight, you can use the direct formula:

$Profit Percentage = (\frac{True Weight - False Weight}{False Weight}) \times 100$

Given values:

$True Weight = 1 kg = 1000 g$
$False Weight = 800 g$

Substitute these values into the formula:

$Profit Percentage = (\frac{1000 - 800}{800}) \times 100$

$Profit Percentage = (\frac{200}{800}) \times 100$

$Profit Percentage = \frac{1}{4} \times 100 = 25%$
