Let us assume number be x.
On dividing first time by 100, we get x/100.
On dividing second time by 100, we get x/ 100/100 = x/10000.
On the same way,
On dividing third time by 100, we get = x/1000000.
And on dividing fourth time by 100, we get = x/100000000.
And we get final result on dividing 4th by 100 = 100.
Putting x/100000000 equals 100, we get
[tex]\frac{x}{100000000} = 100[/tex]
Multiplying both sides by 100, we get
[tex]\frac{x}{100000000} *100000000 = 100 * 100000000[/tex]
x= 10000000000.
So, 10000000000 is the actually number.
Now, dividing 10000000000 first time by 50, we get
= 200000000
Dividing second time by 50, we get
= 4000000.
Dividing third time by 50, we get
= 80000.
And finally dividing fourth time by 50, we get
= 1600.
