Q1. Three numbers which are co-prime to each other are such that the product of the first two is 551 and that of the last two is 1073. The sum of the three numbers is________?
Answer: 85
Explanation: 551 = 19 × 29 and 1073 = 29 × 37, so the common middle number is 29. The three co-prime numbers are 19, 29, and 37; their sum = 85.
