Question
What number: When increased by 15% becomes 230?
✓
Answer
Let the number be $=100$
Increase $=15 \%=15$
$\therefore$ Increased number $=100+15=115$
If increased number is 115 , then original number $=100$
and if increased number is 230 , then original number
$=\frac{100}{230} \times 115=200$
Increase $=15 \%=15$
$\therefore$ Increased number $=100+15=115$
If increased number is 115 , then original number $=100$
and if increased number is 230 , then original number
$=\frac{100}{230} \times 115=200$
