If ab=cd=ef=34{a \over b} = {c \over d} = {e \over f} = {3 \over 4}What is the value of a+c+eb+d+f{a + c + e \over b + d+f}?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 3/4.

Let a, c and e be 3x and b, d and f be 4x.

Now, a+c+eb+d+f{a + c + e \over b + d+f} = 3x+3x+3x4x+4x+4x{3x + 3x + 3x \over 4x + 4x +4x}

⇒ 9/12 = 3/4
