1. Divide Rs.5625 among A, B and C so that A receive 1/2 as much as B & C and B 1/4 of what A and C together receive?

  • A. 1125, 1870, 2630
  • B. 1125, 1870, 2630
  • C. 1125, 1870, 2630
  • D. 1125, 1870, 2630

Answer: Option C

Explanation:

Let they receive A, B & C Rs. respectively.

Now, A = (B + C) / 2

or,  2A = B + C - - - - - - - - - - (i)

Again, B = (A + C) / 4

or, 4B = (A + C)

or, 4B = (B + C) / 2 + C

or, 4B = B/2 + C/2 + C

or, 4B - B/2 = 3C/2

or, 7B/2 = 3C/2

or, B = 3C/7 - - - - - - - (ii)

Now, 2A = 3C/7 + C  [from (i)]

or, 2A = 10C/7

or, A = 5C/7 - - - - - - (iii)

From (ii) and (iii), 

B : C = 3 : 7

C : A = 7 : 5

So,  A : B : C = 5 : 3 : 7

A will receive = 5 / (5 + 3 + 7) × 5625 =  1875 Rs.

B will receive = 3 / (5 + 3 + 7) × 5625 =  1125 Rs.

C will receive = 7 / (5 + 3 + 7) × 5625 =  2625 Rs.
