Let original CP of 1kg = Rs. 1000 ---(1)
Now, as he uses 800g weight for 1kg,
SP of 800g = Rs. 1000
⇒ SP of 1000g (1kg) = 1000 × 1000/800
⇒ SP of 1kg = Rs. 1250 ---(2)
∴ From 1 and 2,
Profit for 1kg = SP – CP
= 1250 – 1000
= Rs. 250
∴ Profit% = 100 × Profit/CP
= 100 × 250/1000
Thus, he makes a profit of 25%
Now, as he uses 800g weight for 1kg,
SP of 800g = Rs. 1000
⇒ SP of 1000g (1kg) = 1000 × 1000/800
⇒ SP of 1kg = Rs. 1250 ---(2)
∴ From 1 and 2,
Profit for 1kg = SP – CP
= 1250 – 1000
= Rs. 250
∴ Profit% = 100 × Profit/CP
= 100 × 250/1000
Thus, he makes a profit of 25%
