A series of 5 terms is 23, 34, 45, 56, 67. If each term is increased by 7 and then decreased by 57% find the ratio of the series then formed. Correct Answer 30 : 41 : 52 : 63 : 74

It is known that if each term of the series is increased by a same percentage the ratio remains the same. The ratio of the new series will be 23 + 7 : 34 + 7 : 45 + 7 : 56 + 7 : 67 + 7 = 30 : 41 : 52 : 63 : 74
