Question

Surya is 25 years older than his son.In 5 years, he will be twice as old as his son.What will be Surya's age after 3 years?

Answer 1

Answer:

let son age =x

surya age = x+25

AFTER 5 YEARS

son age=x+5

surya age =x+25+5

=x+30 ----(1)

by the question after 5 years age of surya is twice of his son

therefore surya age = 2(x+5) ---(2)

equating (1)and (2) we get

x+30=2(x+5)

x+30=2x+10

30-10=2x-x

20=x

therefore son age is 20

surya age is x+25=20+25=45

therefore after 3 years Syria's age is 45+3= 48

Answer 2

$\huge{\boxed{\mathtt{\purple{Answer}}}}$

Sons age = s

Surya's age = x

x=25+s

Also x+5 = 2(s+5)

30+s = 2s+10

s=20

x = 45

In 3 years surya's age will be x+3 =48
