Answer: C) 20 Explanation: Let the rquired number be 'P' According to the question, 100 x P100 = 20=> P = 20 x 100100 = 20 Hence, 100 percent of the number 20 is 20.   Now, you can also try for 20 percent of what number is 100 20 x P100 = 100=> P = 100 x 10020 = 500=> P = 500 Hence, 20 percent of the number 500 is 100.

Answer: D) 93747 Explanation: From the hints, Only two options for 1st and 2nd digits => 4,2 and 9,3 since it is single digits Sum of second and third digit  = 10  If 2 => 3rd digit = 8 If 3 => 3rd digit = 7 4th digit = 2nd digit + 1 => (2+1 =3) or (3+1 = 4) Sum of all digits = 30 Let 5th digit be x => 1st possibility = 4 + 2 + 8 + 3 + x = 30 => x = 13 (Not possible since it has 2 digits) => 2nd possibility = 9 + 3 + 7 + 4 + x = 30 => x = 7 Therefore, the PIN is 93747
