N is increased successively by 12.5% and 16%. If N = 400, then what is the value of the increase?

142 92 172 122

122

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
