The company does not report the Gross Profit directly, hence calculated it as under:

Gross Profit = Revenue - Cost of goods sold

Pg. 181: Consolidated Statement of profit and loss for the year ended March 31, 2020

CONTINUING OPERATION

Revenue from operations - 7,369.00 ₹ in Crores

Cost of raw materials and accessories consumed - 3,300.46 ₹ in Crores

Purchase of stock-in-trade - 365.91

Changes in inventories of finished goods, work-in-progress and stock-in-trade - 69.45

Therefore, Gross Profit = A-B = 7,369.00-(3,300.46+365.91+69.45) = ₹ 3633.18 Crores
