Question 1021418: A grandmother has 4 grandchildren 2 boys 2 girls when you multiply their ages together their product is 67184. Only one is a teenager the oldest is under 40 the difference between the youngest and the oldest ones age is 30 years. What are their ages

67184=2%5E4%2A13%2A17%2A19
A%2AB%2AC%2AD=67184
D-A=30
19%3CB%3CC%3CD%3C40
13%3C=A%3C=19
Given the factorization of 67184, the teenager can only be 13, 16, 17, or 19.
However since D=A%2B30, then D is either 43, 46, 47 or 49, which violates that the oldest is less than 40.
