Height of Sandra that is already mentioned in the question is = 4 feet Percentage by which Pablo is taller than Sandra = 10% Height by which Pablo is greater than Sandra = (10/100) * 4 = (4/10) = 0.4 feet Then height of Pablo is = 4 + 0.4 = 4.4 feet Now we can find the height of Michaela as she is 8% taller than Pablo. Percent by which Michaela is taller than Pablo = 8% Height by which Michaela is greater than Pablo = (8/100) * 4.4 = (2 * 4.4)/25 = 0.35 feet Then the height of Michaela = (4.4 + 0.35) feet = 4.75 feet So height of Michaela is 4.75 feet. This is the way this problem has to be solved.
