The correct answer is (b) ` 59.00.

Explanation:
A bought 13 shirts of 50 each, 15 sweaters of 60 each and 12 ties of ` 65 each.

His total expenditure on shirts = 13 * 50 = 650
His total expenditure on sweaters = 15 * 60 = 900
His total expenditure on ties = 12 * 65 = 780
His total expenditure on all the items = 650 + 900 + 780 = 2330
His average expenditure per article = 2330 / (13 + 15 + 12) = ` 59.00

Option (a) is incorrect because it is the average expenditure per shirt. Option (c) is incorrect because it is the average expenditure per sweater. Option (d) is incorrect because it is the average expenditure per tie.
