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:  Pick one: A) 80 B) 85 C) 90 D) 95 E) 100
Let three numbers are a, b and c.   Given:   The product of a and b is 551.   The product of b and c is 1073.   b is common in both the product   b = H.C.F. of 551 and 1073 = 29;   a = (551/29)=
