30 Dec 2009 mark sheet printing mistake

Marks of Physics are printed in reverse order in the mark sheet of Surjeet. If printed marks are
less than the correct marks and he gets 67 % after this mistake then which % out of these options is
incorrect for the correct mark sheet (It is given that Surjeet gets success either according to
mark sheet obtained or according to corrected mark sheet. Total marks of the examination are 500)

OPtion

1) 74.2
2) 76.0
3) 70.6
4) 72.4
5) 79.6
6) 68.8
7) 77.8

Solution

In this reverse printing procedure possible conditions are as given below
Correct marks Printed marks Difference 43 34 9
53 35 18
54 45 9
63 36 27
64 46 18
65 56 9
73 37 36
74 47 27
75 57 18
76 67 9
83 38 45
84 48 36
85 58 27
86 68 18
87 78 9
93 39 54
94 49 45
95 59 36
96 69 27
97 79 18
98 89 9
Therefore possible increments in % are 1.8, 3.6, 5.4, 7.2, 9.0, 10.8
Hence the solution is 79.6 % with
increment of 12.6 %.

In case of 79.6% marks,

Difference of marks will be 63 .
Which is possible for 92/29 and 81/18 in physics.

29 and 18 does not qualify for success.
