selling price of 7 articles. J1 = Average cost price per article J2 = Total value of profit earned on article A, B and C What is the respective ratio of J1 and J2?Solution
J1 = (525 + 430 + 640 + 540 + 340 + 775 + 600)/7 = 550 The total cost price of A, B, and C = 525 + 430 + 640 = 1595 The total selling price of A, B, and C = 675 + 520 + 700 = 1895 The profit of A, B and C = J2 = 1895 - 1595 = 300 Â The ratio of J1 and J2 = (550/300) = 11:6
