Good trick

Question:
Rs.1,087 is divided among A, B, and C such that if Rs 10, Rs 12 and Rs 15 are diminished from the share of A, B and C respectively, the remainders will be in the ratio of 5, 7 and 9. What is the share of B?
Options:
A) Rs 362
B) Rs 355
C) Rs 465
D) Rs 260
Solution:
Ans : (a) Rs [1,087 – (10 + 12 + 15)] or Rs 1,050 is to be divided in the ratio 5 : 7 : 9

So, B’s share = \(\cfrac{7}{21}\) × 1,050 = Rs 350 

Therefore, B’s total share = 350 + 12 = Rs 362.
