If 63.9805=6A+3/B+9/C+8/D+5E

Then 4A+7B+6C+D+3E equals to?

Answer 1

Answer:

147.6003

Step-by-step explanation:

Given: 63.9805 = 6A + (3/B) + (9/C) + (8/D) + 5E

⇒ 60 + 3 + 0.9 + 0.08 + 0.0005 = 6A + (3/B) + (9/C) + (8/D) + 5E

On comparing the terms, we get

60 = 6A, 3 = (3/B), 0.9 = (9/C), 0.08 = (8/D), 0.0005 = 5E.

A = 10, B = 1, C = 0.1, D = 100, E = 0.0001

Now,

Given: 4A + 7B + 6C + D + 3E

= 4(10) + 7(1) + 6(0.1) + 100 + 3(0.0001)

= 40 + 7 + 0.6 + 100 + 0.0003

= 147.6003.

Hope it helps!
