Question

other, find the numbers.
10. Rajeev is 5 times older than his son. After 2 years sum of
ages will be 40. Calculate their present ages.​

Answer 1

Step-by-step explanation

Let age of Rajeev be =  x

Let the age of his son be =  y

given , Rajeev is 5 times older than is son

       so,  x = 5y                    (1)

AFTER 2 YEARS

RAJEEV   (x+2)

Son           (y+2)

According to the question

x+2+y+2=40

5y+2+y+2=40                (from (1))

6y+4=40

6y=40 -4

6y= 36

y= 36/6

y= 6

From equation 1

x = 5y

x = 5x 6

x = 30

therefore age of rajeev is 30 and age of his son is 6

Hope this helps!!!!!!!!!!

Answer 2

Answer:

Rajeev's age is 30 and son's age is 6.

Step-by-step explanation:

Let the son's age be 'x' ...............(I)

Acc. to 1st condition,

Rajeev's age= 5x ...............(ii)

Acc. 2nd condition,

Age of son = x+2

Age of rajeev= 5x+2

Rajeev's age + son's age = 40

(5x+2) + (x+2) = 40

6x +4 = 40

6x = 40 - 4

6x = 36

x = 36/6

therefore, x = 6

Now,

Son's present age =6 ............from (I)

Rajeev's present age =5x

= 5×6

Rajeev's present age = 30

Therefore, Rajeev's age is 30 and son's age is 6.
