Correct Answer: Assertion is correct, but the reason is false.

Solution : The correct answer is (d) Assertion is correct, but the reason is false.

The assertion that programs help in coordinating activities among various departments is correct. Programs are often designed to coordinate and align the efforts of different departments or units within an organization to achieve common goals.

Therefore, the assertion is correct, but the reason is false.

Correct Answer: Both statements are true.

Solution : The correct answer is (A) Both statements are true.

Statement 1: If a good is a luxury, its demand is generally elastic. This statement is true. Luxury goods are often associated with higher income levels and are considered non-essential or discretionary purchases. As a result, consumers are more sensitive to changes in the price of luxury goods, and the demand for luxury goods tends to be more elastic.

Statement 2: Luxury goods tend to have more substitutes, making consumers more responsive to changes in price. This statement is also true. Luxury goods often have a variety of substitute products available in the market. When the price of a luxury good increases, consumers have more options to switch to alternative products, which increases their responsiveness to price changes. This higher availability of substitutes contributes to a more elastic demand for luxury goods.

Both statements accurately describe the relationship between luxury goods, price responsiveness, and elasticity of demand.

Correct Answer: 3 units

Solution : Let one side of a right-angled triangle be $x$.
Shortest side = $x-1$
Longest side = $x +1$
Since the three sides form a right-angled triangle.
$(x+1)^2=(x-1)^2+x^2$
⇒ $x^2+1+2x=x^2+1-2x+x^2$ 
⇒ $x^2=4x$
⇒$x=4$
Thus, shortest side = $x-1=4-1=3$
Hence, the correct answer is 3 units.
