Question

Sandra is 4 feet tall. Pablo is 10% taller than Sandra, and Michaela is 8% taller than Pablo.

Explain how to find Michaela's height with the given information

Answer 1

If you would like to know how tall is Michaela, you can calculate this using the following steps:

Sandra ... s = 4 feet tall
Pablo ... p = 10% taller than Sandra: 110% * s = 110% * 4 = 110/100 * 4 = 4.4 feet tall
Michaela ... m = 8% taller than Pablo: 108% * p = 108% * 4.4 = 108/100 * 4.4 = 4.752 feet tall

Result: Michaela is 4.752 feet tall.

Answer 2

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.
