Question

A lady has 25p and 50p coins in her purse.If in all she has 80coins totalling rs.25 how many coins of each kind does she have?

Answer 1

Let number of 25p coins be x .
No. of 50p coins = 80-x.
Now,
25*x + 50(80-x) = 25*100
25x + 4000 - 50x = 2500
25x = 1500
x = 1500/25 = 60.
Thus, No. of 25 paise coins is 60 and
No. of 50 paise coins will be 80-60 = 20 .

Answer 2

Answer:

25-P coins = 60

50-P coins = 20
