The Number X Is Exactly Divisible By 5 And The Remainder Obtained On

1.	The Number X Is Exactly Divisible By 5 And The Remainder Obtained On Dividing The Number Y By 5 Is 1. What Remainder Will Be Obtained When (x + Y) Is Divided By 5 ?
Answer» LET x/5 = p and let y when divided by 5 gives Q as quotient and 1 as remainder. Then, y = 5Q + 1 Now x = 5p and y = 5q + 1 x + y = 5p + 5q + 1 = 5(p + q) + 1. Let x/5 = p and let y when divided by 5 gives q as quotient and 1 as remainder. Then, y = 5q + 1 Now x = 5p and y = 5q + 1 x + y = 5p + 5q + 1 = 5(p + q) + 1.

Answer»

LET x/5 = p and let y when divided by 5 gives Q as quotient and 1 as remainder.

Then, y = 5Q + 1

Now x = 5p and y = 5q + 1

x + y = 5p + 5q + 1 = 5(p + q) + 1.

Let x/5 = p and let y when divided by 5 gives q as quotient and 1 as remainder.

Then, y = 5q + 1

Now x = 5p and y = 5q + 1

x + y = 5p + 5q + 1 = 5(p + q) + 1.
