for question 20, (1/2) will be the answer...this is because if we put d=1/3 then a=2*(k-1)/3 which can be either an even integer or any other fraction..it cannot be a prime number..put the other values of d and u will find the same..only for d=1/2, a=(k-1)/2 which can be a prime number...so option a...!!!!!
