This is one of the easy model in number system for bank exam. Here the question is in the form of fractions, don't think about fraction questions in bank exams, i will explain how to solve this type of problems. let us discuss model 6 problems based on number systems.

Example 24:
Explanation:
From the question given fractions are 9/17, 7/23, 11/21 and 13/19
Now will arrage these fractions in to ascending order:
Step 1:  Compare 9∕17 with 7∕23.  now do the Cross Multiplication  it means 9 x 23  and 17 x 7
             207  > 119 so 9∕17 is greater than 7∕23
now write in to ascending order  7∕23, 9∕17

Step 2: Compare 9/17 with 11∕21  Repeat the Step 1 again do cross multiplication, 9 x 21 and 17 x 11
           9 x 21 > 11 x 17
now write in to ascending order  7∕23,11∕21, 9∕17,

Step 3: Compare 9/17 with 13/19 again do cross multiplication and check the greater number
            9 x 19   and  17 x 13
            17 x 13 > 9 x 19
now write in to ascending order  7/23, 11/21, 9/17, 13/19
