Question

Five years ago, Nuri was thrice as old
as sonu. Ten years later Nuri will be
twice as old as sonu. How old are Nuri
and sonu​

Answer 1

Answer:

Nuri"s age is 30 years

Sonu's age is 10 years

Step-by-step explanation:

let Nuri's age is x years and sonu's age is is y years

acc... to question

x=3y...(1)

x+10=2 (y+10)

x+10=2y+20

3y+10=2y+20(x=3y)

y=10

x=3 (10)

x=30

Answer 2

Let us assume, the present age of Nuri is x.

And the present age of Sonu is y.

According to the given condition,

we can write as;

x – 5 = 3(y – 5)

x – 3y = -10 ……..(1)

Now,

x + 10 = 2(y +10)

x – 2y = 10 ……….(2)

Subtract eq. 1 from 2, to get,

y = 20 ……….(3)

Substituting the value of y in eq.1,

we get;

x – 3(20) = -10

x – 60 = -10

x = 50

Therefore,

• Age of Nuri is 50 years
• Age of Sonu is 20 years.
