If the sales team earned a profit of Rs 433 on each mock
tests sold of SBI PO during September, what was his total profit earned on the mock tests of that exam during the same month? Study the following pie-chart and table carefully and answer the questions given below: Percentage wise distribution of the number of mock tests sold by a sales team of Ixambee during six months. Total number of mock tests sold = 45,000 The ratio between the numbers of mock tests sold of RBI Grade B Officer and SBI PO during six months.Solution
Number of mock tests sold in the month of September = 8% of 45000 = 3600 ∴ Number of mock tests sold of SBI PO in the month of September = 3600 × 5/12 = 1500 ∴ Total profit earned by the selling SBI PO in the month of September = 1500 × 433 = 649500
