Question

If 1/2x +1/4x+1/8x=14 Then the value of x is:
(a) 8
(b) 12
(c) 4
(d) 16

Answer 1

If x is in numerator then here is your answer,

X/2+x/4+x/8=14

7x/8=14

x=16...

Hope it helps you....

Answer 2

To solve this,take LCM

$\frac{1}{2}x + \frac{1}{4}x + \frac{1}{8}x = 14 \\ \\ \frac{4x + 2x + x}{8} = 14 \\ \\ \frac{7x}{8} = 14 \\ \\ 7x = 14 \times 8 \\ \\ x = \frac{14 \times 8}{7} \\ \\ x = 2 \times 8 \\ \\ x = 16$
Thus,value of x = 16.

Option D is correct.
