A number is decreased by 10% and then increased by 10%. The number so obtained is 10 less than the original number. What was the oiginal number ?

Question

Accepted Answer

Let the original number be x. Final number obtained = 110% of (90% of x) =(110/100 * 90/100 * x) = (99/100)x. x-(99/100)x=10 => x =1000
