policeman is chasing a thief. Find the time required to catch
{A} policeman is 2 times faster.
{b} DISTANCE BETWEEN THEM IS 20 m

• both statement are insufficient to find time because neither speed of thief nor speed of police is given.

• Both statements are in sufficient as for t= d/ s, but here we have relation given, suppose speed of thief is X so police will be 2X so relative speed will be 2X - X = X,
  So t = d/ X = 20/x,so not possible.

• Insufficient,
  explanation=for the very first we need to assume speed of both the thief=x and policemen=2x,
  than they are going in the same direction so the relevant speed is 2x-x=x,
  and than the formula is Time=distance/speed which is now time = 20/x "so for time we need value of x"

• Both statement is insufficient. To find time we need Distance/Speed, so we have distance 20 m but speed has not numerical specific value.

• We need exact values of there speed, we cannot find out on ratio basis. So both statement are insufficient.
