Answer 1

the answer for these is 100

Answer 2

Answer:

150

Step-by-step explanation:

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

Then, sum of their values

=> Rs. ( 25*x/100 + 10*2x/100 + 5*3x/100) = 30

=> Rs. (25x / 100 + 20x / 100 + 15x / 100)  30

=> Rs. (60x/100) = 30

=> x = 30 * 100 / 60 = 100 / 20 = 50

=> x = 50

Hence,thenumberof5pcoins

=> 3x

=> (3×50)

=> 150
