Question : When a number is increased by 112, it becomes 170% of itself. Find the number.
Option 1: 160
Option 2: 150
Option 3: 200
Option 4: 180
Correct Answer: 160
Solution :
Let the number be $x$.
According to the question,
$x+112=x×\frac{170}{100}$
$⇒10x+1120=17x$
$⇒7x=1120$
$\therefore x = 160$
Hence, the correct answer is 160.
