Q: Roshan bought 5 pants at ₹25 each, 10 shirts at ₹ 50 each and 15 ties at ₹ 35 each. Find the average price of all the articles.

Here, n1 = 5, n2 = 10, n3 = 15, a1 = 25, a2 = 50, a3 = 35 According to the formula, Average price = (n1a1 + n2a2 + n3a3) / (n1 + n2 + n3) = (5 x 25 + 10 x 50 + 15 x 35) / (5 + 10 + 15) = (25 + 100 + 105) / (1 + 2 + 3) = 230/6 = ₹ 38.33

₹ 38.33
₹ 45
₹ 60
₹ 45.33

Correct Answer: ₹ 38.33

Explanation:

Here, n₁ = 5, n₂ = 10, n₃ = 15, a₁ = 25, a₂ = 50, a₃ = 35
According to the formula,
Average price = (n₁a₁ + n₂a₂ + n₃a₃) / (n₁ + n₂ + n₃)
= (5 x 25 + 10 x 50 + 15 x 35) / (5 + 10 + 15)
= (25 + 100 + 105) / (1 + 2 + 3)
= 230/6
= ₹ 38.33
