A. 50 B. 100
C. 150 D. 200

• 25X+10(2X)+5(3X)=3000
  60X=3000
  X=50
  5P=3X=50*3=150

• ratio is 1:2:3
  so 25+15+20=60 ps.
  60 ps =>3 (5p coins)
  3000 ps => ?
  (3000/60)*3=150 coins.

• 1(25)+2(10)+3(5)=60p
  in bag Rs 30 are there =60p*50
  so to get Rs 30 we need 50 sets of 1:2:3 coins
  50*1=25p coins are 50
  50*2=10p coins are 100
  50*3=5p coins are 150

• 25p 10p 5p
  1/4p +1/5p +3/20p=30
  12p=600
  1p=50
  3*50=150
