Answer 1

Answer:

1. It is given that when a Number is divided by 80 then it leaves remainder 20.⠀
2. What will be remainder when the same number will be divided by 16.⠀
3. We can see that 16 will divide 80 completely in 3 times, so 16 will must divide that Number in the same manner.⠀
4. All we need to check what will be remainder when the we divide remainder i.e. 20⠀

⠀

$\sf16 \:)\:20 \:( \:1 \\ {\qquad\!\sf16}\\ - - - - - \\{ \qquad\:\sf4}$

⠀

We can see that we get 4 as remainder when we divide the rest remainder of first division.

⠀

$\therefore\:\underline{\textsf{It will give \textbf{4} as remainder when divided by 16}}.$

$\rule{200}{1}$

Points to remember :

• The second divisor (Here 16) should must divide the first divisor (Here 80) completely.
• After that Simply divide the first remainder (Here 20) by second divisor (Here 16).
• Whatever remainder will be obtained, that is our Answer.
