• A. $2:5$
• B. $2:3$
• C. $1:5$
• D. $2:7$

Answer 1

Answer: (A)

$2:5$

$\Rightarrow$ Let the first number is $A$ and second number is $B$.

$\Rightarrow$ As per question,

$\Rightarrow$ $A=40\%ofB$

$\Rightarrow$ $A=\frac{40}{100}B$

$\Rightarrow$ $\frac{A}{B}=\frac{2}{5}$

$\therefore$ $A:B=2:5$
