Answer» HEYA!! ---------- Let SISTERS age be X MARY's age = 2X After 5 years. ( X+ 5 ).+ 2 = ( 2X +5) X +5 +2=2X +5 X+7-2X-5=0 -X +2 =0 -X =-2 X=2 Hence sisters age is 2 years Mary's age is = 4 years . ----------------------------------------------------------------------------------------------------- ☺✴✴ |
