Mental math approach:
35% of the total is used in ad, 18% of ad is used in radio. Therefore, 18% of 35% of the total is used in radio ad.

D. 35.0%



r = Radio expenditure = 18% of (ad expenditure) = 0.18 * a .....(1)

a = ad expenditure = 35% of (total expenditure) = 0.35 * t .....(2)

using (2) in (1)

r = 0.18 * a = 0.18 * 0.35 * t = 0.063 * t

Now finish it....
