ArithmeticPercentage, Profit & Loss
What is the percentage of a cloth that should be exactly from 40 metre cloth so that the remaining portion is 7 metre?
- a.17.5
- b.19
- c.82.5
- d.81
Answer: (C) 82.5
If the remaining portion is 7 metres, then the portion cut = 40 - 7 = 33 metres. Percentage cut = $\frac{33}{40} \times 100 = 82.5\%$. The question asks for the percentage that should be cut, not the remaining percentage.
