- 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.
Question 1:
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:
A. 85
Feedback Since the numbers are co-prime, they contain only 1 as the common factor.
Also, the given two products have the middle number in common.
So, middle number = H.C.F. of 551 and 1073 = 29;
First number = 551/29 = 19; Third number = 1073/29 = 37.
Required sum = (19 + 29 + 37) = 85.
