A series of 4 digits with the terms 55, 66, 77 and 88 is first arranged in descending order and increased in the following way 20%, 40%, 60% and 120%. Find the ratio of the new series formed. Correct Answer 48 : 49 : 48 : 55

The series in descending order = 88, 77, 66, 55 The new series = 88 + 20% of 88, 77 + 40% of 77, 66 + 60% of 66 and 55 + 120% of 55 The new series = 88 + 17.6, 77 + 30.8, 66 + 39.6 and 55 + 66 The new series = 105.6, 107.8, 105.6 and 121 The ratio = 1056 : 1078 : 1056 : 1210 = 48 : 49 : 48 : 55
