Question

five years ago Nuri was thrice old as manu ,ten years later ,Nuri will be thwice old as manu.the present age in years of Nuri andanu are respectively​

Answer 1

Let the present age of Nuri =x year

And present age of manu =y year

Five years ago

Age of Nuri =x–5years

Age of man =y–5years

Nuri was thrice as old as manu

X−5=3(y–5)

X–5=35–15

X–3y=−15+5

X–3y=−10 ………..(1)

Ten years later,

Age of Nuri =x+10

Age of manu =y+10

Nuri will be twice as old as manu

X+10=2(y+10)

X+10=2y+20

X–2y=10 ………..(2)

X–3y=−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 manu =20 years
