Arvind has a kiddy Bank. If is full of one rupee coin and fifty paise coin. If contains three times as many fifty paise coins as one rupee coin. The total amount of money in the bank is 35 how coins of each kid thare in bank.

Answer 1

50 paise coin *3 = 1 rupee coin
total money is 35
let no. of 1 rupee coin be x
 and the no. of 50 paise coin be 31
x+3x=35
but 2 coins of 50 paise make 1 rupee
so,
     x+3x/2= 35
   2x+3x/2= 35
            5x= 35*2
            5x= 70
              x=70/5
              x=14 
no. of 1 rupee coin = x = 14
no. of 50 paise coin = 3x =3*14 =42
