A + B + C + DMath brain teasers require computations to solve.A, B, C, and D are all positive whole numbers. If A is to 2 as B is to 3; B is to 6 as C is to 8; and C is to 9 as D is to 12, what is the SMALLEST possible value for the sum: A + B + C + D ?
HintA/2 = B/3 or 3A = 2BB/6 = C/8 or 8B = 6C ; C/9 = D/12 or 12C = 9D . What's the smallest positive whole numbers that satisfies all three of the above equations? Hide What Next?
