Question

a And b are friends and their ages differ by 2 years is father d is twice as old as a and b is twice as old as his sister see the ages of d and c differ by 4 years find the ages of a and b​

Answer 1

Let the ages of A = x years

and

age of B = y years.

Since, their ages differ by 2 years.

x - y =2 (Assuming A is older than B) -------------------(i)

Now, A's father D is twice as old as A,

Age of D = 2x years.

and

B's is twice as old as his C,

Age of C =

Also, the ages of D and C differ by 40 years.

∴On solving equations (i) and (ii) , we get,

Put the value of x in (i) we get

⇒ 26 - 2 = y

⇒ y = 24 years = B's age

∴Age of A is 26 years and B is 24 years.

Answer 2

Let the ages of A = x years

age of B = y years.

Since, their ages differ by 2 years.

x - y =2 (Assuming A is older than B) -------------------(i)

Now, A's father D is twice as old as A,

Age of D = 2x years.

and

B's is twice as old as his C,

Age of C =

Also, the ages of D and C differ by 40 years.

?On solving equations (i) and (ii) , we get,

? 26 - 2 = y

? y = 24 years = B's age

?Age of A is 26 years and B is 24 years.
