Solution

The correct option is E
None of these

A = $2 B$

$\Rightarrow b = \frac{1}{2} A$

so, $A B = \frac{2}{25} \Rightarrow \frac{1}{2} A^{2} = \frac{2}{25} \Rightarrow A^{2} = \frac{4}{25} \Rightarrow A = \frac{2}{5}$

In a pair of positive fractions, fraction A is twice the fraction B and the product of two fractions is 225,the value of fraction A is?

The correct option is E None of these A =2B ⇒b=12A so, AB=225⇒12A2=225⇒A2=425⇒A=25
