Pargat Pal Singh   11 years AGO

1% of x= 1/100 of x = 10^(-2) of x

so for every 1% of x , final value is 10^(-2) of x

so 1% of 1% of ...... 1% ( 30 times) of 1 = 10^(-60) of 1

Devendra Marghade   11 years AGO

For every 1% of the previous value we have 10^-2
Therefore to get 10^-60, we need to have 30 numbers of operations of 1%

sagar arora   11 years AGO

As 10^-60 means 1/10^60 or 1/(100)^30
1% of 1 means 1/100
so 1/(100)^30 =10^-60

1/100 = 10^-2
so, in order to get 10^-60 there should be 30.

To get 10^-2 There should be one "1%of" in the equn
To get 10^-60 There should be 30 "1%of" in the equn

nitin madaan   11 years AGO

by solving
1% of 1 is 1*(1/100)=10^-2
so if we do that 30 times thn 10^-60 will be the answer

Ajay Kashyap   11 years AGO

1% of 1 = 10^-2
so 10^-2*10^-2*10^-2 ans so on.....
10^-2-2-2 ...so on = 10^(-2)30
so answer is 30 times

1/100=.01
(1/100)^30=10^-60

MANOJ KUMAR SHARMA   11 years AGO

1%=10^-2,hence 30 such 1% will be required to get 10^-60

srikantam samyuktha   11 years AGO

1% can be written as 10^-2 and 10^-60 can be written as 1/10^60;10^2x = 10^60 --> 2x=60 --> x=30

IQBAL MEHDI   11 years AGO

from the last,1% of 1=10^-2
again,1% of 10^-2=10^-4,and so on.

phani   11 years AGO

1%=1/100=10^-2
1%of 1%of 1=10^-4=(10^-2)^2((2times)
similarly:10^-60=(10^-2)^30
so 1%of is used 30 times

Like? Yes (1) | No   

Rakesh Kumar Kohli   11 years AGO

10^-60 = (10^-2)^30
which shows 1% of is written 30 times in the question.

Kamalraj   11 years AGO

For 1% of 1 ,we will write it as 1*1/100=10^-2 . Therefore for thirty times 1% of1=10^-60

Balakrishnan M   11 years AGO

1% of 1 = 1/100 = 10^-2
1% of 1% of 1 = 1/100 * 1/100 = 10^-4= (10^-2)^2
.....1%of 1%of 1%of 1%of 1%of 1% (upto 30 times)of 1 = 10^-60 = (10^-2)30
