    Solution

    ATQ,

    Let the cost price of blue shirt be Rs. 'x' So, cost price of black shirt = Rs. (x + 40) And, cost price of green shirt = Rs. (x - 20) ATQ, Or, x + x + 40 + x - 20 = 380 Or, 3x + 20 = 380 Or, 3x = 360 So, 'x' = 120 So, sum of selling prices of black and blue shirt = (x + x + 40) × 0.75 = 1.5x + 30 = (1.5 × 120 + 30) = Rs. 210 Selling price of green shirt = 1.3 × (x - 20) = 1.3 × (120 - 20) = Rs. 130 Therefore, total selling price= 130 + 210 = Rs. 340
