Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. IV

Option I

⇒20+20−20×20100=40−4=36%\Rightarrow 20 + 20 - \frac{20 \times 20}{100} = 40 - 4 = 36\%

Option II

⇒25+15−25×15100=40−3.75=36.25%\Rightarrow 25 + 15 - \frac{25 \times 15}{100} = 40 - 3.75 = 36.25\%

Option III

⇒30+10−30×10100=40−3=37%\Rightarrow 30 + 10 - \frac{30 \times 10}{100} = 40 - 3 = 37\%

Option IV

⇒5+35−5×35100=40−1.75=38.25%\Rightarrow 5 + 35 - \frac{5 \times 35}{100} = 40 - 1.75 = 38.25\%
