25, 10, 5 paise coins are in the ratio of 1:2:3 .if their total value is Rs.30 , then the number of 5 paise coins is?
[A] 150
[C] 50
[B] 80
[D] 100

• 25x+20x+15x=3000
  60x=3000
  x=50
  so no of 5 paise coin=50*3=150

  coz, if 150 nos of 5 paisa, thn 100nos of 10 paisa and 50 nos of 25 paisa by the ratio 1:2:3
  150 nos of 5 paisa means 7.50rs
  100 nos of 10 paisa means 10rs
  50 nos of 25 paisa means 12.50rs

• x/4 + 2x/10 + 3x/20=30
  x=50
  number of 5 paise coin =3*50=150

• first of all we will multiply ratio of coin with here value so that it will amount to RS 300
  (0.25*1)x+(0.10*2)x+(0.05*3)x=30
  we will get x=50
  now, amount of 5 paise coin = o.15x50 = RS 7.5
  but we have to get no. of coins so dividing amount by its value
  7.5 /0.05 = 150
