For a mobile phone, the selling price, cost price and
marked price are in the ratio 9:6:12. If a profit of Rs. 1500 is earned, what is the discount given on it?Solution
ATQ,
Let the selling price, cost price and marked price be Rs. 9x, Rs. 6x and Rs. 12x respectively
According to the question,
Profit earned = 9x – 6x = Rs. 3x
Therefore, 3x = 1500
Or, x = 500
Therefore, discount offered = 12x – 9x = 3x = 3 × 500 = Rs. 1500
