Answer:
1500 × 20 ÷ 100
= 300
so first we have find 20 % and subtract it from 1500
= 1500 - 300
= 1200
so the original number is 1200
Step-by-step explanation:
Let the number be x
find the number after increase:
increase of 20% = 20% of x = 0.2x
number = x + 0.2x =1.2x
SOLVE X :
The number is 1500
1.2x = 1500
x = 1500/1.2
x = 1250
