The present ages of Lewis and Brown are in the ratio 1:2. Three years from now, the ages will be in the ratio 3:5. Find the present ages of Lewis and Brown.

• l:b=1:2 & (l+3):(b+3)=3:5
  then 2l=b & 5l+15=3b+9
  by solving above we get
  l=6 & b=12

• Lewis(l)/brown(b)=1/2,L+3/b+3=3/5, on solving Lewis has 6 and brown has 12 years at present.

• short trick
  
  brown = 2 * 3 (3-5)/(6-5) = 12
  lewis = 1* 3 (3-5)/(6-5) = 6

• Let present ages= x and 2x then..
  X+3/2x+3=3:5
  Solve we get x=6 and since ratio is 1:2 other age(brown) is 12
