see the B is improved why because
their is increase in 2 marks of B from 10 to 12 and the percentage of increase is 20%
i.e.,2/10*100=20%
whereas A is increased in 2 marks from 12 to 14 and the percentage of increase is 16%
i.e.; 2/12*100=16%
their is increase in 2 marks of B from 10 to 12 and the percentage of increase is 20%
i.e.,2/10*100=20%
whereas A is increased in 2 marks from 12 to 14 and the percentage of increase is 16%
i.e.; 2/12*100=16%

B's improvement=(new marks-original marks)/original marks *100%
= (12-10)/10*100%=20%
A's improvement=(new marks-original marks)/original marks*100%
=(14-12)/12*100%=16.6666666666666666666%
therefore, B showed more improvement(though increase in marks are equal,percentage is completely different)
= (12-10)/10*100%=20%
A's improvement=(new marks-original marks)/original marks*100%
=(14-12)/12*100%=16.6666666666666666666%
therefore, B showed more improvement(though increase in marks are equal,percentage is completely different)
