There are a number of cuffs and collar pieces which belong to freddy and charlie. there total is 30. freddy and charlie gave all of them to the laundry. freddy collects half the number of cuffs and one-third the number of collars and pays his share of 27 cents. 4cuffs costs 5collars.now tell how much did charlie

• let the TOTAL number of the cuffs be X
  let the TOTAL number of the COLLARS BE be 30-X
  NOW FREDDY COLLECTS 1/2*X + 1/3*(30-X) = X/6 + 10
  so charlie would collect 1/2*X + 2/3*(30-X) = -X/6 + 20
  by inspection and trial and error we can see that X=12
  now putting X=12 in first equation we get 12 and puttin in eqn 2 we get 18
  there fore freddy pays 27cents for 12 pieces
  so charlie will pay ____ cents for his 18 pieces
  THE ANSWER WILL BE 40.5 CENTS

• cuff+collar=30
  from the data we can assess that cuff is a multiple of 2 so no.of cuffs=12
  and collar is multiple of 3 so collar=18
  1/2*12cuff+1/3*18collar=27 and 4cuff=3collar solving them we get cost of each. finally the ANSWER is 39CENTS

  from the data we can assess that cuff is a multiple of 2 so no.of cuffs=12
  and collar is multiple of 3 so collar=18
  freddy:
  1/2of the collar=6
  1/3of the cuffs=6
  6t+5/4*6t=27
  t=2
  then charlie:
  6*2+5/4*12*2=42 cents

• let the TOTAL number of the cuffs be X
  let the TOTAL number of the COLLARS BE be 30-X
  NOW FREDDY COLLECTS 1/2*X + 1/3*(30-X) = X/6 + 10
  so charlie would collect 1/2*X + 2/3*(30-X) = -X/6 + 20
  by inspection and trial and error we can see that X=12
  now putting X=12 in first equation we get 12 and puttin in eqn 2 we get 18
  freddy pay 27 for 6 cuff & 6 collors (4cuff=5colllor i.e. 6 cuff= 7.5 collar)
  freddy pay 2 cents for each collor and 2.5 for each cuff
  so charli will pay 6*2.5(cuffs)+12*2(collors)=39
