There are many benefits to timing your practice, including:

because r is positve so q will also be positive from here only way r can be less than q is when q is more than 1. becasue -rq is less than 2 that means

rq> 2. so there is no way q can be less than 1.

so this statement is sufficient to answer that r>q

statement 1 says -r*q/2<1 or -rq<2 because r is positve so q will also be positive from here only way r can be less than q is when q is more than 1. becasue -rq is less than 2 that means

rq> 2. so there is no way q can be less than 1.

so this statement is sufficient to answer that r>q

satement 2 says

1/r < 1/q

unless r is negative ( which r is not)

r>q from this equation.

so B is sufficient.

so our answr choice is D

buddy, the second bold part should be rp>-2. Btw, I agree with Himalaya that OA is B.

From 1 we get -rq < 2 or rq > -2 . r=q^2 substituting we get q^3>-2, we can find values for Q which satisfies and which also not satisfies this property. Hence A is not sufficient.

1/r < 1/Q => r > Q Hence statement 2 is sufficient.
