A has double the money of B and B has 50% more money then C. If average money of all the three persons is ₹ 12000, how money does A have ?
-
- ₹ 211000/11
- ₹ 315000/11
- ₹ 216000/11
- ₹ 316000/11
- None of the above
Correct Option: C
Let money of C be ₹ N.
According to the question
Total money of B = N + N x 50%
= N + 50N/100 = 3N/2
Total money of A = 2 x 3N/2 = 3N
Average money of three persons = 12000
∴ Total money of three = 12000 x 3
∴ 3N + (3N/2) + N = 12000 x 3
⇒ (6N + 3N + 2N)/2 = 36000
∴ N = (36000 x 2)/11 = 72000/11
Now, money of A = 3N = (3 x 72000)/11
= ₹ 216000/11
