Question

5 year ago new Nuri was thrice and old as Sonu 10 years later new Nuri will be twice as old as Sonu how old are NUri and Sonu​

Answer 1

Answer:

sonu's age is 20 years now

and nuri's age is 50 years

Step-by-step explanation:

5 years ago,

let sonu's age be x

nuri's age be 3x

10 years from now means 15 years from 5 years before

sonu's age = x + 15

nuri's age = 3x +15

but given nuri's age is twice sonu's age so,

2(x + 15) = 3x + 15

2x + 30 = 3x + 15

3x - 2x = 30 - 15

x = 15

x is the age 5 years ago

sonu's age now = x+5=15+5=20

nuri's age=3x 5 years ago

nuri's age now = 3x+5=3×15+5=45+5=50

Answer 2

${\huge{\bold{\boxed{\tt{\color{magenta}{answer}}}}}}$

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 Nuri is 50 yearsAge of Sonu is 20
