There are three numbers, these 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. What will be the sum of three numbers :
Answer: C
As given the questions these numbers are co primes, so there is only 1 as their common factor.
It is also given that two products have the middle number in common.
So, middle number = H.C.F. of \(551\) and \(1073 = 29\)
So first number is : \(\frac{551}{29} = 19\)
Third number = \(\frac{1073}{29} = 37\)
So sum of these numbers is,
\(= \left ( 19 + 29 + 37 \right ) = 85\)
