  • Question

  • If 47. 2506 = 4*A + 7/B + 2*C + 5/D + 6*E, then the value of 5*A + 3*B + 6*C + D + 3*E is :


  • Options
  • A. 55.6003
  • B. 53.603
  • C. 153.6003
  • D. 213.003

  • Correct Answer
  • 153.6003 

    Explanation

    4*A + 7/B + 2*C + 5/D + 6*E =47.2506
    => 4 * A + 7/B + 2 *C + 5/D + 6*E = 40 + 7 + 0.2 + 0.05 + 0.0006
    Comparing the terms on both sides, we get :
    4*A =40, 7/B = 7, 2*C = 0.2, 5/D = 0.05, 6*E = 0.0006
    A = 10,
    B = 1,
    C = 0.1,
    D = 100,
    E = 0.0001.
    5*A + 3*B + 6*C + D + 3*E =(5*10) + (3*1) + (6*0.1) +100 +(3*0.0001)
    =50 + 3 + 0.6 + 100 + 0.003 = 153.6003.
