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:1). 752). 853). 654). 45

Answer»

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

∴ Sum of the three numbers is 85
