Answer:
let the age of tanzin = 3x
let the age of tashi =2x
FIVE YEARS FROM NOW
let the age of tanzinfive years from now = 3x+5
let the age of tashi years from now= 2x+ 5
5 years from now the ratio of their ages will be 4:3, so
3x+5/2x+5 = 4/3
by cross multiplication method
9x+15=8x+20
9x -8x= 20-15
X=5
thus ,
present age of tanzin =3x =3×5=15y
present age of tashi =2x =2×5= 10 y
