What is the age of father if the sum of the ages of a father and his son in years is 65?

If the sum of the ages of a father and his son in years is 65 and twice the difference of their ages in years is 50, then the age of the father is – 45 years. 40 years.

What is the age of father if the sum of the ages of a father and his son in years is 65 and thrice the difference of their ages in years is 75?

⇒y=603=20 Years. Now from equation (2) we have, ⇒x=2(20)+5=40+5=45 Years. So the present age of the father is 45 years and his son is 20 years.

Is 6 times his son’s age?

Let ‘x’ year be the present age of father and ‘y’ year be the present age of son. Putting y = 6, we get x = 36. Hence, present age of father is 36 years and age of son is 6 years.

What is the age of father if the sum of the ages of a father and his son is here is 65 and twice the difference of their ages in years is 50?

Therefore, option (b) 45 years is the correct answer.

Are linear and simultaneous equations the same?

Two linear equations in two variables taken together are called simultaneous linear equations. The solution of system of simultaneous linear equation is the ordered pair (x, y) which satisfies both the linear equations.

How do you calculate combined age?

This can be solved using the equation X + Y =36 and X +7 + Y + 7 = 4Y so we know in 7 years X + Y= 50 by substitution if son is 1 dad is 35 in 7 years son will be 8 and Dad will be 42 so currently son is 1 and Dad is 35. Originally Answered: The combined ages of a father and his son are 36.

What is the formula for age problems?

Important Statements and Equations for “Problems based on Ages”: If the present age is y, then n times the present age = ny. If the present age is x, then age n years later/hence = x + n. If the present age is x, then age n years ago = x – n.

What will be the age of the father after four years?

Four years hence, the age of the father will be four times his son’s age. The present ages, in years, of the son and the father are respectively,

What is the ratio of a father to his son?

Thus the ratio is 7:3 and the correct option is D) 7:3. Q 1: The age of a man is 24 years more than his son. In two years, the father’s age will be twice that of his son. Then the present age of his son is:

What is an example of sum of age?

Example 1: A father and his son decide to sum their age. The sum is equal to sixty years. Six years ago the age of the father was five times the age of the son. Six years from now the son’s age will be: A) 23 years B) 19 years C) 20 years D) 22 years Answer: Suppose that the present age of the son is = x years.

How do you write the father’s age after 15 years?

Since we were able to write all 4 expressions with just one variable, we will only need one equation. And we will write this equation using the only relationship we have not used already: “after 15 years, the father will be twice as old as his son at that time”. In other words: The father’s age in 15 years will be twice the son’s age in 15 years.
