Question

A bag contest coins of 25paise and 50 paise in such a way that the total mamount is 120. If the number of 25 paise coins is thrice the number of 50 paise coins find their number (number of 25paise coins =288. Number of 50 paise coins =96).

Answer 1

Answer:

Let there are X one rupee's coin, Y 50 paise's coins and Z 25 paise's coins.

Now,

X +Y +Z = 220 ---------------- (1)

Total amount = Rs. 160

Now,

X + (Y/2) + (Z/4) = 160

4X +2Y +Z = 640 ---------------- (2)

Thrice as many 1 Re coins as 25 paise,

X = 3Z -------- (3)

On Solving equations 1, 2 and 3,

Z = 40

X = 3*40 = 120

Y = 220 - (120+40)= 60

50 paise's coins = 60.
