    Solution

    Number of Chocolate cookies baked on Monday and Tuesday = 250 – (25 + 100) = 125 On Tuesday Chocolate cookies baked were 50% more than as compare to that Monday. Ratio of Chocolate cookies baked on Monday to Tuesday = 2:3 So, 5 ------ 125 => 2 ------ 50 => 3 ------- 75 Number of Chocolate cookies baked on Monday = 50 Number of Chocolate cookies baked on Tuesday = 75 Butter cookies baked in these four days were y% less than that on each day and total Butter cookies baked were 50. => 250 – 50 = 200 => y% = (200/250) × 100 = 80% On Monday Chocolate Cookies baked were x% more than as compare to Sunday. => x% = [(50 – 25)/25] × 100 = 100% Number of Butter cookies baked on Sunday = 20% of 25 = 5 Number of Butter cookies baked on Monday = 20% of 50 = 10 Number of Butter cookies baked on Tuesday = 20% of 75 = 15 Number of Butter cookies baked on Monday = 20% of 100 = 20 There are two possibilities. Therefore, the answer cannot be determined.
