Question

pls solve this problem​

Answer 1

Answer:

40

Step-by-step explanation:

let age of sonu's father be y and age of son be x.

can be represented by equation

y =4x. - (i)

after 5 years

sonu's father's age will be 3 times his age.

and sonu's age at that time will be (x+5)

so equation will be

y+5 = 3(x+5)

y+5 = 3x +15

y-3x = 10. - (ii)

from (i) and (ii)

4x - 3x = 10

x = 10

so his father's age is 4x = 4 × 10 = 40
