Question

Ted weighs twice as much as Julie. Mike weighs three times as much as Julie. Together, Ted, Mike, and Julie weigh 210 lbs. What is the weight of each person?

Answer 1

- Julie weighs 35 lbs
- Mike weighs 105 lbs
- Ted weighs 70 lbs

Answer 2

In this problem, Julie is the basis for figuring it out.

J = Julie's Weight

Ted = 2j
Mike = 3j

2j + 3j + j = 210 or 6j

210 ÷ 6 = 35

With this, we know Julie's weight. Also, that she might as well be skin and bones.

35 × 2 = 70

35 × 3 = 105

105 + 70 + 35 = 210

Julie's Weight = 35 lbs.
Ted's Weight = 70 lbs.
Mike's Weight = 105 lbs.
