If a/b = 2, b/c = 3, c/d = 4, d/e = 3, e/f = 2 and f/g = 1.5, then what is the value of (a + b + c)/(e − f + g)?

Explanation
Take g = 2; then f = 1.5 x 2 = 3, e = 2 x 3 = 6, d = 3 x 6 = 18, c = 4 x 18 = 72, b = 3 x 72 = 216, a = 2 x 216 = 432. Then (a+b+c)/(e-f+g) = (432+216+72)/(6-3+2) = 720/5 = 144.
