Answer 1

Step-by-step explanation:

Let the number of 25 p, 10 p and 5 p coins be x,2x, 3x respectively.

Then,

25p = x,

10p = 2x,

5p = 3x.

Now,

25p = 25/100 = 1/4;

10p = 10/100 = 1/10;

5p = 5/100 = 1/20;

Given, there are 30 in all.

=> 1x/4 + 2x/10 + 3x/20 = 30

=> 5x + 4x + 3x = 600;

=> 12x = 600 (3*50)

=> x = 150

Therefore,

Number of 5p coins = 150

Hope it helps!
