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 :

• A. 153.6003
• B. 253.6003
• C. 353.6003
• D. None of these

Answer: (A)

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 = 0.0006A = 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.
