A number is multiplied by 5 and 25 is added to it. The result is divided by 5 and the original number is subtracted from the quotient. What will be the remainder?
Let the number be x, its multiplied by 5 and 25 added to it.
So, the result is (5×x)+25
The result is divided by 5, so the quotient is (5×x)+255
Then, remainder is =(x×5)+255−x as x is subtracted from the quotient.
=5x+25−5x5
