If 40% of a number is equal to two-third of another number, what is the ratio of first number to the second number?
a)2 : 5
b)3 : 7
c)5 : 3
d)7 : 3

• If first no is x and other no is y , then
  
  x*40/100 = y*2/3
  x/y = 2*100/120 = 200/120 = 5/3
  
  so ratio is 5:3 ...... option c

• let the 1st number be x.
  then 40% of it is 40/100*x = 2/5 * x.
  Now another number be y.
  then according the pblm, take 2/3 * y
  x:y = 5:3
  therefore option c is correct.
