Study the given pie-chart and answer the question that follows.
The chart represents the percentage-wise distribution of total number of vanilla cakes and chocolate cake sold every day in a week. Total number of cakes sold in a week = 10500.
The ratio of vanilla cakes sold to chocolate cakes sold on Friday is 4 : 3. If the selling price of one vanilla cake is Rs 9 and that of one chocolate cake is Rs 10, then the total amount earned (in Rs) by selling all the vanilla cakes and chocolate cakes on Friday is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 9,900
Solution :
The total cakes sold on friday = (10/100) × 10500 = 1050
The ratio of vanilla cake to chocolate cake on friday = 4 : 3
Hence the number of chocolate cakes sold on friday = (3/7) × 1050 = 450
And the number of vanilla cakes sold on Friday = 1050 - 450 = 600
The total amount earned (in Rs) by selling all the vanilla cakes and chocolate cakes on Friday = (9 × 600) + (10 × 450) = 5400 + 4500 = Rs. 9900.
