Question
What number: When increased by 10% becomes 88?
✓
Answer
Let the number be $=100$
Increase $=10 \%=10$
Increased number $=100+10=110$
If increased number is 110 , then original number $=100$
and if increased number is 88, then original number
$=\frac{100}{110} \times 88=80$
Increase $=10 \%=10$
Increased number $=100+10=110$
If increased number is 110 , then original number $=100$
and if increased number is 88, then original number
$=\frac{100}{110} \times 88=80$
