Find the marginal revenue if the average revenue is 45 and elasticity of demand is 5.
उत्तर
Given, average revenue (RA) = 45 and
elasticity of demand (η) = 5
Rm = RA `(1 - 1/η)`
∴ Rm = `45 (1 - 1/5) = 45(4/5)`
∴ Rm = 36
∴ Marginal revenue (Rm) = 36

A manufacturing company produces x items at a total cost of ₹ 40 + 2x. Their price per item is given as p = 120 – x. Find the value of x for which revenue is increasing
Solution: Total cost C = 40 + 2x and Price p = 120 – x
Revenue R = `square`
Differentiating w.r.t. x,
∴ `("dR")/("d"x) = square`
Since Revenue is increasing,
∴ `("dR")/("d"x)` > 0
∴ Revenue is increasing for `square`
