Q. A new apartment complex purchased 60 toilets and 20 shower heads. If the price of a toilet is three times the price of a shower head, what percent of the total cost was the cost of all the shower heads?

Option
a) 9%
b) 10%
c) 11%
d) 13%
e) 15%

• ANS:10%
  LET PRICE OF SHOWER HEADS=X
  THEN ,, ,, TIOLETS=3X
  TOTALCOST=20*X+60*3X=200x
  % OF TOTAL COST WAS THE COST OF ALL THE SHOWER HEADS=(20X/200X)*100=10%

• 60 toilet=180 shower heads
  total shower heads=180+20=200
  so cost is=200/20=10

• b) 10%
  If the cost of toilet=x & shower head=y
  Total cost=60x+20y, Given x=3y
  So Total cost=60*3y+20y=200y
  % of Shower head cost to total cost=20y/200y=10

  Let x be the cost of shower head. Hence 20x is invested in shower head.
  6083x=180x is invested in toilets. Total= 180x+20x=200x
  Hence % cost of the shower head=20x/200x*100=10%

• price of one toilet x then 60 toilets=60x
  price of one shower y then 20 shower=20y
  given that x=3y
  60 toilet=180
  20/180*100=11

  den cost of 1 toilet=3x
  total cost=180x+20x=200x
  den 20x*100/200x
