Answer 2

The profit % would be 37.5%.

Step-by-step explanation:

Since we have given that

Profit % = 10%

He uses 20% less weight

So, R = 10%

r = 20%

So, the profit % would be

$\dfrac{R+r}{100-r}\times 100\\\\=\dfrac{10+20}{100-20}\times 100\\\\=\dfrac{30}{80}\times 100\\\\=37.5\%$

Hence, the profit % would be 37.5%.
