Is rs = rx − 2 ?

(1) r is an odd number

(2) x = s + 2

rs = rx − 2 can be restated as

r(x-s) = 2 -----(1)

Statement 1r is odd, Still we don't know the value of (x-s).

Thus Insufficient

Statement 2This is very tempting option for many of us.

(x-s)=2.

we don't know the value of r.

Thus Insufficient

Statement 1& 2r= odd (can take any odd value 1, 3, 5 etc)

(x-s)=2.

r(x-s) will equal 2 only if r=1. But we don't know value of r for sure

Thus Insufficient

Answer E
