   ∵ 90A/100 = 30B/100 = (30/100) x AC/100

   Correct Option: D

   ∵ 90A/100 = 30B/100 = (30/100) x AC/100
   ∴ C = 100 x (100/30) x (90/100) = 300

   33¹/₃% = (100/3) /100 = 1/3 =0.33;
   4/15 = 0.26
   Clearly 0.35>0.33>0.26

   Correct Option: C

   33¹/₃% = (100/3) /100 = 1/3 =0.33;
   4/15 = 0.26
   Clearly 0.35>0.33>0.26
   ∴ 0.35 is greatest
