Three numbers which are co-primes to one another 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
Answer & Explanation
Answer : Option C |
|
Explanation : |
|
Let the numbers be a, b and c.
ATQ, a$\times$ b = 551
b $\times$ c = 1073
b = HCF of 551 and 1073 = 29 a $\times$ b = 551
a = $551 \over b$ = $551 \over 29$ = 19
b $\times$ c = 1073
c = $1073\over 29$
c = 37
Sum = 19 + 29 + 37 = 85 |
