Answer:

Son is 3. Father is 33.

Step-by-step explanation:

Let the present age of the son be 'x' years.

Then father's age will be (x + 30) years

Given : After 12 years, the father will be three times as old as his son. Therefore,

(x + 12)3 = x + 30 + 12

3x + 36 = x + 42

3x - x = 42 - 36

2x = 6

x = 3

The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.

Separate 72 into 2 parts, one of which shall be 1/3 of the other
prisoha [69]

Answer:

The second part of 72 is (\frac{215}{3})

Step-by-step explanation:

The whole part is given  as  = 72

One part of it = 1/3

Let  the other part of it  = k

Now,according to the question:

First Part + Second Part = 72

or, k +  (\frac{1}{3})   = 72

⇒k   = 72  -   (\frac{1}{3})

or, k   =   (\frac{216 -1}{3})  \implies k = \frac{215}{3}

or, k = 215/3

Hence, the second part of 72 is (\frac{215}{3})
