    Solution

    Number of chocolates in box тАШAтАЩ = 140 ├Ч (4/20) = 28 Number of chocolates in box тАШBтАЩ = 140 ├Ч (7/20) = 49 Number of chocolates in box тАШCтАЩ = 140 ├Ч (9/20) = 63 Now, new ratio of number of chocolates in box тАШAтАЩ, тАШBтАЩ and тАШCтАЩ = (28 + 4):(49 тАУ 4 + 3):(63 тАУ 3) = 32:48:60 = 8:12:15
