Question
If the selling price of a red pen, a blue pen and a
black pen is Rs.20, Rs.15 and Rs.25 respectively, then find the total revenue generated by shopkeeper C by selling all the three types of pens. Answer the questions based on the information given below: The table shows the sum of the number of red pens and blue pens sold, number of blue pens sold as percentage of number of red pens sold and the ratio of number of blue pens sold to the number of black pens sold respectively by 4 different shopkeepers.Solution
For shopkeeper A, Let the number of red pens sold be ‘x’. Then, the number of blue pens sold = 55% of x = 0.55x Now according to question, => x + 0.55x = 310 => x = 200 Number of red pens sold = 200 Number of blue pens sold = 0.55x = 110 Number of black pens sold = 110 × (9/11) = 90 Similarly, we can find the required data for the other shopkeeper too. 
Total revenue generated by shopkeeper C = (100 × 20) + (120 × 15) + (168 × 25) => 2000 + 1800 + 4200 = Rs.8000 Â
