\(m\) divided by 5- remainder 2 so \(m\) can be - 2 , 7 , 12 , 17 , ...
\(n\) divided by 5- remainder 1 so \(n\) can be - 1 , 6 , 11 , 16 , ...
Qt A
remainder when \(m + n\) are divided by 5.
In all cases, remainder will be 3
Qt B
remainder when \(mn\) is divided by 5
In all cases, remainder will be 2
Qt A > Qt B
Answer A
\(n\) divided by 5- remainder 1 so \(n\) can be - 1 , 6 , 11 , 16 , ...

Answer A
Can you please elaborate on this? For Quantity A, say m=12 and n=11. 23/5 should give a remainder of 2, since the next closest multiple is 2 away?
