Option 1: 168
Option 2: 152
Option 3: 144
Option 4: 170
Correct Answer: 168
Solution : Given: The sum of the two numbers is 400. Let the bigger number and the smaller number be $x$ and $y$ respectively. ⇒ $x+y=400$ (equation 1) According to the question, $x-\frac{16}{100}x=y+\frac{16}{100}y$ ⇒ $\frac{84}{100}x=\frac{116}{100}y$ ⇒ $84x=116y$ $\therefore x=\frac{116}{84}y$ Substitute the value in the equation 1, ⇒

Option 1: 18%
Option 2: 20%
Option 3: 22%
Option 4: 24%
Correct Answer: 22%
