If a = 4q+r, and r= 1 then possible value "a" of the following.
A) 6
B) 8
D) 11
C) 9​

Answer 1

$\huge\star{\tt{\underline{\underline{\red{Answer}}}}}\star$

a=4q+r

r=1

a=4q+1

when q=1

a=4 x 1 +1

a= 5

when q=2

a= 4 x 2 +1

a= 9

when q = 3

a= 4 x 3 +1

a=12

Here we are exceeding the options

so we have an answer

when q= 2

a will probably have a value of 9

So Possible value of a can be 9
