10. Rajeev is 5 times older than his son. After 2 years sum of
ages will be 40. Calculate their present ages.
Answers
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:
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.
