Question

is 'p' is prime number and a is any number such that (a,p)=1, then a is correct option

Answer 1

Answer:

Let us take some examples

If P =3 then(p+2)=5⇒p(p+2)+1=3×5+1=16

If P =5 then(p+2)=7⇒p(p+2)+1=5×5×7+1=36

If P=11 then (P+2)=13 ⇒p(p+2)+1=11×13+1=144

All the resulting numbers are perfect squares so (c) is the correct option
