Answer:
The number of cases prior to the increase in measles = 53
Step-by-step explanation:
The increase in rate of measles case = 10.2%
The total number of cases after 10.2 % increase = 58
The number of cases before 10.2 % increase in measles case = ??
Let x be the no of cases present before 10.2 % increase.
x * (100 + 10.2) % = 58
x * 110.2 % = 58
x = 58 / 110.2 = 52.63
x = 53 (rounded off)
