The ratio of ages of two friends is 3:5 and sum of their ages is 80 years. What are their present ages in years?

a) 10,60
b) 20,60
c) 40,30
d) 30,50

• 3x + 5x== 80
  x==10
  (30,50)

• ratio=3:5
  sum=80
  i.e 8parts=80 (3+5=8parts)
  so 1part=10
  3parts=30
  5parts=50

• 3a+5a=80 then a= 10
  ages are 30, 50

• (d) given ratio is 3,5 . hence assume 3x,5x..... now 8X=80
  X=10
  hence
  3x=3(10)=30
  5X=50

• d
  3x+5x=8x
  8x=80
  x=80/8=10
  3x=3*10=30
  5x=5*10=50
