A number is first increased by 40% and then it is increased by 30%. What is the net percentage increase?
Answer & explanation
Correct answer: option 1
Let Initial Number = 100x
According to question ,
New number = 100x × \(\frac{100+40}{100}\) × \(\frac{100+30}{100}\)
= 100x × \(\frac{140}{100}\) × \(\frac{130}{100}\)
= 182x
Required percentage = \(\frac{182x - 100x }{100x}\) × 100 = 82%
