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) 75 B) 81
C) 85 D) 89
sol>since the second no. is common in both products , it must be factor of
both 551 and 1073 ... i.e. 29 so the no .will be 551/29 and 1073/29 i.e.
19,29 and 37 .... so sum is 85
