Answer 1

Answer:

Step-by-step explanation:

Let the number of 50P coins be x.

Let the number of 25P coins be 4x.

Now,

Value of 50P coin = rs.x/2

Value of 25P coin = rs. 4x/4 = rs.x

Now, forming the equation,

x/2 + x = 30

⇒3x/2 = 30

⇒3x = 60

⇒x = 20

Therefore, no. of 25P coins is 80 and that of 50P coins is 20.
