Question

Five year ago,nuri was trice as old as sonu ten year later,nuri will be between twice as old as sonu how old as nuri and aonu

Answer 1

hi apko ye solution Sahi laga to brainlist bna dijye..




Let the present age of Nuri  = x year

And present age of Sonu = y year

Five years ago

Age of Nuri = x – 5 years

Age of Sony = y – 5 years

Nuri was thrice as old as Sonu

X- 5  =  3(y – 5)

X – 5  =  35 – 15

X – 3y  =  -15  + 5

X – 3 y  = - 10                        ………..(1)

Ten years later,

Age of Nuri  = x + 10

Age of Sonu = y + 10

Nuri will be twice as old as Sonu.

X+ 10 = 2(y+10)

X + 10  = 2y + 20

X – 2y  = 10                           ………..(2)

X – 3 y  = - 10                        ………..(1)

Subtracting equation (1) from equation (2)  we get

Y  = 20

Plug this value in equation first we get

X  - 3* 20 = -10

X = 60 – 10

X  = 50


Hence age  of Nuri = 50 years and age of Sonu = 20 years



thank u
