Question

If p=2q then q=r*r , if p-odd then q is even, whether r is even or odd ?

Answer 1

The options for this question are missing:

a) First condition is sufficient

b) Second condition is sufficient

c) Both are sufficient

d) Both are not sufficient

Solution:

1)p=2q then q=r*r

2)p-odd then q is even

consider r=3(odd),the r^2=9(answer is odd)

consider r=4(even),the r^2=16(answer is even)

so Both are not sufficient
