Rs. 1,820 are divided among A, B and C. The share of A is 2/5 of the combined share of B and C. Then A gets how much amount?
Explanation:
Let shares of A, B and C be a, b and c respectively.
⇒ a + b + c = 1820
Also, a = 2/5(b + c) ⇒ b + c = 5a/2 Substituting b + c in (1) we get
a + (5a/2) = 1820 ⇒ 7a/2 = 1820 ⇒ a = 1820 × 2/7 = 520
Hence, option (d).
