Answer:
The value of number is 82.5
Step-by-step explanation:
Given as :
Let The number = x
∴ 25.6 % of x = 21.12
Or, 25.6 × x = 21.12 × 100
Or, 25.6 × x = 2112
∴ x = 
i.e x = 82.5
Hence 25.6 % of 82.5 is 21.12 So , The value of number is 82.5 Answer
% is 1/100 part of whole
so 1% is 200/100=2
and 8% is 2*8=16
or
200/100*8=2*8=16
or
200*0.8=16
Answer: 16
Answer:
