A) 9

B) 10

C) 12

D) 18

Correct Answer: C

Solution :

[c] Let, first number \[=x\] and second number \[=y\] According to the question,

\[xy=48\] ...(i)

and \[x=\frac{2+5\times 2}{3}=\frac{2+10}{3}\]

\[x=\frac{12}{3}-4\] \[\Rightarrow \]\[x=4\]

Now, putting the value of x in Eq. (i), we get

\[4\times y=48\]\[\Rightarrow \]\[y=\frac{48}{4}=12\]\[\Rightarrow \]\[y=12\]

\[\therefore \] Second number = 12
