No change in Number if A number increased by 25% and then decreased by 20%
Step-by-step explanation:
Let say number = 100N
Number increased by 25 %
so number after increase = 100N + (25/100)100N
= 100N + 25N
= 125N
Now 125N is Decreased by 20%
so Number after Decrease = 125N - (20/100)125N
= 125N - 25N
= 100N
100 N = 100N
hence there is no Change in the number
