Answer»

Solution

Given that :-

  • Five years ago, Nuri was thrice as OLD as Sonu
  • Three years letters Nuri will be TWICE as old as Sonu

Find :-

  • Present AGE of Nuri & Sonu

Explanation

Let,

  • Present age of Nuri = x years
  • Present age of Sonu = y years

A/C to question,

(Five years ago, Nuri was thrice as old as Sonu )

➡ (x -5) = 3 × (y-5)

➡ x - 3y = -15 + 5

➡ x - 3y = -10 _________(1)

Again,

(Three years letters Nuri will be twice as old as Sonu)

➡ (x+3) = 2 × (y+3)

➡ x - 2Y = 6 - 3

➡ x - 2y = 3 __________(2)

Subtract equ(1) & equ(2)

➡ -3y + 2y = -10 - 3

➡ -y = -13

➡y = 13

Keep value of y in equ(2)

➡ x - 2*13 = 3

➡x = 3 + 26

➡x = 29

Hence

  • Present age of Nuri ( x ) = 29years
  • Present age of Sonu ( y) = 13 years
