Question

Anwar has ₹34 in 50paise and 25paise. If the number of 25paise coin be twice the number of 50paise coin.How many coins of each kind does he have?

Answer 1

let no. of 25 paise coin be X
and no. of 50 paise coin be y
according to question,
X=2y....,........1st equation
now, total money=34 rupees
so, X/4 + y/2 =34
or it can be written as X+2y=136..........2nd equation
on using 1st in 2nd
4y=136
y=34 and X=68
