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?	Choose the most appropriate option.
A) 33
B) 76
C) 85
D) 22
E) 99
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=

<output>19</output>
19   Third number= 1073/29= 
<gadget id="calculator">1073/29</gadget>
<output>37</output>
37.   Required sum= 19 + 29 + 37= 
<gadget id="calculator">19 + 29 + 37</gadget>
<output>85</output>
85.   Answer:85
