As you know according to Chargaff rule, DNA from any cell of organism should have 1:1ratio base pair, or it means Purine= Pyrimidin. from the question we get that amount of guanine and cytosine would be 40%.since guanine makes bond with cytosine then both would have same amount. Hence the individual amount of guanine is 20%.All the best.
