Answer 1

$\mathbb{\pink{\huge{Hello\:Mate!!!}}}$

$<b><u>Answer</u></b>$

$<b>(C) 30 and 10</b>$

$<b><u>Step-by-step explanation</u></b>$

Given that, x = 13 and y = 39. As x and y are directly proportional to each other, the highest common factor between them = $\frac{x}{y}$

HCF = $\frac{13}{39}$

HCF = $\frac{1}{3}$

HCF = 1:3

(A) HCF of 1 and 3 = 1:3

(B) HCF of 17 and 51 = 1:3

(C) HCF of 30 and 10 = 3:1

(D) HCF of 6 and 18 = 1:3

$<b>Therefore, (C) 30 and 10 is not possible.</b>$


Thanks......!
