Question
What number: When decreased by 40% becomes 480?
✓
Answer
Let the number be $=100$
Decrease $=40 \%=40$
$\therefore$ Decreased number $=100-40=60$
If decreased number is 60 , then original number $=100$
and if decreased number is 480 , then original number $=\frac{100}{480} \times 60=800$
Decrease $=40 \%=40$
$\therefore$ Decreased number $=100-40=60$
If decreased number is 60 , then original number $=100$
and if decreased number is 480 , then original number $=\frac{100}{480} \times 60=800$
