Question

the present age of ramu's father is four times to ramu's age. After 10 years sum of their ages is 70 years . find the present ages
​

Answer 1

Answer:

ramu's age = 10

father's age= 40

Step-by-step explanation:

ramu's age= x

father's age= 4x

after 10 years= x+10+4x+10=70

5x+20=70

5x= 70-20= 50

x=50/5 =10

so ramu's age is 10 his father 40

Answer 2

Answer:

Ramu's present age = 10 years

His father's present age = 40 years

Step-by-step explanation:

Let Ramu's present age be x.

Thus, his father's present age will be 4x.

According to question:

After 10 years, Ramu's age will be (x+10) and his father's age will be (4x+10).

=>(x+10) + (4x+10) = 70

=> 5x + 20 = 70

=> 5x = 50

=> x = 10 [ Ramu's present age ]

4x = 40 [ Ramu's father's present age ]

Hope this helps...
