Given : A number increase by 9% followed by a 6% decrease?
To Find : single decimal multiplier to represent the same
Solution:
Let say Number = 100N
increase by 9%
= (9/100)100N
= 9N
Number after increase = 100N + 9N = 109N
6% decrease
= (6/100)109N
= 654N/100
= 6.54N
After Decrease final number = 109N - 6.54N
= 102.46N
= 10246N/100
= 10246 * 100N/100 * 100
= 10246 * 100N/10000
= 1.0246 * 100N
1.0246 multiplier will be used to increase by 9% followed by a 6% decrease
