Bala had 240 cards and Tom had 780 cards.After Tom gave some cards to Bala, Bala had twice as manycards as Tom.How many cards did Tom give to Bala?

Answer»

let the GIVEN cards be x

therefore total cards with bala =240+x

cards with tom =780-x

2(240+x) = 780-x

420+2x= 780-x

2x+x = 780-420

3x = 360

x = 360/3

x = 120

∴cards with bala = 240+120=360

cards with tom = 780 - x

                          = 780 -120

                         =660
