a.b>a
b.b<a
c.b=a
d.b>=a

Answer 1

Hope this helps you

Answer 2

$Given \: a \: and \: b \: are \: positive \\</p><p>integers \: and \: \frac{(a-b)}{3.5} = \frac{4}{7}$

/* Multiplying both sides by 3.5 , we get */

$\implies \frac{(a-b)}{3.5} \times 3.5 = \frac{4}{7}\times 3.5$

$\implies a-b= 4 \times 0.5$

$\implies a-b= 2 \: ( positive \: number )$

$\implies \pink { a > b}$

$\implies \pink { b < a}$

Therefore.,

$Option \: \pink { (b) } \: is \: correct .$
