If two numbers are in the ratio 5:2. If 20 is subtracted from both of the numbers then the ratio becomes 4:2 then find the smallest number?	Select:
A) 30
B) 20
C) 40
D) 50
E) 12
5:2   5x - 20 : 3x - 20 = 4 : 2   2[5x - 20] = 4[3x - 20]   10x - 40 = 12x - 80   12x - 10x = 80 - 40   x = 20   Then smallest number is = 2x   2x = 40   40
