N is increased successively by 12.5% and 16%. If N = 400, then what is the value of the increase?
Answer & explanation
Correct answer: option 4
According to question ,
Increased number = 400 × \(\frac{112.5}{100}\) × \(\frac{116}{100}\)
= 400 × \(\frac{4.5}{4}\) × \(\frac{29}{25}\)
= 522
Required Increment = 522 - 400 = 122
