Directions (6-10)- Following questions are based on the five three digit number given below.

437    543    954     593     754

  1. One subtracted from the first digit and two is subtracted from third digit of each of the numbers. What will be the difference between  second digit of the highest number and the sum of first and third digit of lowest number thus formed ?
    A)  4
    B)   5
    C)   3
    D)  2
    E)   1
    View Answer
      Option C

  2. If all the numbers are arranged in descending order from left to right,which of the following will be the product of the first and second digit of the number which is 2nd from left end in new order?
    A)  54
    B)  35
    C)   34
    D)   72
    E)  24

    A)  19
    B) 17
    C)  20  
    D)  22
