If price of Good X is Rs. 5 and that of Good Y is Rs. 4. Find the slope of Budget line.

$-\frac{5}{4}$

The correct answer is option (3) : $-\frac{5}{4}$

The slope of the budget line should be calculated as the negative ratio of the prices of the two goods (Good X and Good Y). The formula is :

Slope of Budget Line = $-(\frac{\text{Price of Good X}}{\text{Price of Good Y}})$

Given :

Price of Good X (Px) = Rs. 5

Price of Good Y (Py) = Rs. 4

Now, we can calculate the slope :

Slope of Budget Line =$ -(\frac{5}{4})=-\frac{5}{4}$

So, the correct answer is (3) $-\frac{5}{4}$
