Statement 1: Let the price of the hockey stick be ‘h’ an ball be ‘b’. Given, h + b = 650 Statement 2: Price of the hockey sticks is Rs. 20 more than twice the cost of the ball. h = 20 + 2b Substituting this, 20 + 2b + b = 650 b = 210 h = 440 Data in both the statements is necessary to answer the question. Hence, option 3 is the correct answer.
