i have a doubt in the first step......if we hold the value of Ann as 'x' then the amount of money tia has will be x + 90. after Ann gave $15 to tia, tia's value wil be x + 90 + 15. and tia's money is thrice of Ann's. so 3 times ann = Tia's money= x + 90 + 15.......
cross check:
after ann gave $15, she will have $60 . it is given that tia's money is thrice of ann. tia now has 75+90+15= 180. and it is thrice of ann.....so pls clear my doubt. thankyou
