Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 9,900
Total no of cake = 10500
Total % of cake sold in a week = 100%
100 % = 10500
1% = 105
now total sold cake on Friday = 10 105 = 1050
The ratio of vanilla cakes sold to chocolate cake on Friday is 4:3, let vanilla = 4x & chocolates is 3x
4x+3x = 1050
x = 150
price of vanilla and chocolate per cake = 9 Rs and 10 Rs
the total amount earned ( in Rs) by selling all vanilla cakes and chocolate cakes on Friday is = (4 x 150 x 9 ) + (3 x 150 x 10) = 5400+4500 = 9900
