Question

Appu is 10 years older than ammu.after 5 years appu's age would be double that of ammu.what are their ages now?

Answer 1

Answer:

20 and 10

Step-by-step explanation:

let appu's age is x

and ammu's age is y

given x=y+10... eq1

x+5=2(y+5).... eq2

x+5=2y+10

x=2y+5... eq3

equating eq1 and eq3 we get

y+10=2y+5

y=5

x=15

their present ages are 20 and 10

Answer 2

Answer:

ammu's age= 5 years

appu's age= 15 years

Step-by-step explanation:

present age,

let ammu's age = x

appu's age = x+10

after 5 years,

ammu's age = x+5

appu's age = x+10+5

=x+15

according to the question,

2(x+5) = x+15

2x+10 = x+15

2x-x = 15-10

x = 5

ammu's age= 5 years

appu's age= 15 years
