Solution :
There are 12% of students studying Economics.
⇒ The total number of students in economics = $\frac{12\times 5000}{100}$.
The number of boys students in Economics = 56% of the total students in economics
⇒ The number of boys students in Economics = $\frac{5000\times 12\times 56}{10000}$
The ratio of the number of boys in Economics to the number of students in Economics = $\frac{5000\times 12\times 56}{10000}:\frac{12\times 5000}{100}$
= 14 : 25
Hence, the correct answer is 14 : 25.
