Hurush wanted to subtract 5 from a number Unfortunately he added 5 instead of subtracting Find the percentage change in

Answer is 2)66.66%

Let us assume the number to be x.
According to the question:
(x-5) was made as (x+5) by mistake.

Now let us find the difference between the two i.e. (x+5)-(x-5)=10
To take the percentage:
10/(x-5)*100=?

It is quite rightly said in one of the answers that x determines the value of the above expression but since there is no such option in the question, we start assuming the value of x. let us assume x to be 20:

10/(20-5)*100=10/15*100=66.66%.

let the number be 10...
then change in result is (10+5)-(10-5)=10
%change= 10*100/15=66.66%

let the number is=10;
adding 5,we get =15;
so percentage change in the number= (15-10)/10=0.5*100%=50% ans

ans is 33.33% bcoz ...if i take x as 10.. % for x+5=15 by using formulae, diff/actual *100 =5/15*100=33.33%

let the no be 10.
10-5=5
10+5=15
change=15-5=10;
change in %=(15-5/15)*100=66.66%

let assume the number is 10...
