A basket contains Rs 216 in the form of one rupee, 50 paise and 25 paise coins in the ratio of 3 : 4 : 4. The number of 50 paise coins is ?
Choose the correct choice from the following:
A) 96  B) 128  C) 144  D) 100  E) 90
Let number of one rupee coins = 3K   Number of 50 paise coins = 4K   Number of 25 paise coins = 4K   Therefore 3K + 0.50 x 4K + 0.25 × 4K = 216   =&gt; 3K + 2K + 1K = 216   =&gt; K = 36   Therefore number of 50 paise coins = 4K = 144   ANSWER:144
