I m 3 times as old my sister. nine years later, I shall be one and a half times as old as my sister. what is my present age?​

Answer 1

Answer:

sorry your question is wrong as if we take your age after 9 years be 3/2 of your sister after 9 years, the ans comes negative 10 but if we take your age as 10 or -10 the ans is correct. hope it helps plz mark as branlist

Step-by-step explanation:

let your age be x and your sisters be y

x=3y ------1

9+x=(1.5)(y+9) -------2

by 1,2

9+x=(1.5)(((1/3)+x)+9)

9+x=(1.5)((1+3x+27)/3)

9+x=0.5*(3x+28)

9+x=1.5x+14

x=1.5x+5

-0.5x=5

x=-10
