The sum of the ages of Mr Lin and his son Ethan is 38 years. In three years' time, Mr Lin will be three times as old as his son.

Sati [7]

Answer:

Mr.Lin's present age is 30 years now. His son is 8 years old now.

Step-by-step explanation:

Let L = Mr.Lin's present age,

S = his son's present age.

First equation is

L + S = 38. (1)

The second equation is

L + 3 = 3*(S+3) (2) ("In three years' time, Mr.Lin will be three times as old as his son.")

From (1), express S = 38-L and substitute it into (2). You will get

L + 3 = 3*((38-L)+3), or

L + 3 = 114 - 3L + 9,

4L = 114 + 9 - 3,

4L = 120,

L = 30.

EXPLANATION

The total number of students can be calculated by adding all the frequencies.

From the graph the total frequency is,

$39+117+78+26 =260$

The number of students who intend to go into state or local government after graduation is 78.

The percentage of students who intend to go into state or local government after graduation

$= \frac{78}{260} \times 100\%$

$= \frac{3}{10} \times 100\%$

$= 30\%$
