Understanding Application

Improvement = (Difference between X class marks and Xll class marks)

If the difference is maximum then she improves maximum,.

Sunita's X class marks = 98

Sunita's Xll class marks = 86

Difference = Xll - X = 86 - 98 = -12 

Veena's X class marks = 85

Veena's Xll class marks = 90

Difference = Xll - X = 90 - 85 = 5

Meena's X class marks = 62

Meena's Xll class marks = 71

Difference = Xll - X = 71 - 62 = 9 

Shivani's X class marks = 79

Shivani's Xll class marks = 82

Difference = Xll - X = 82 - 79 = 3

Alka's X class marks = 72

Alka's Xll class marks = 86

Difference = Xll - X = 86 - 72 =  14

Madhu's X class marks = 76

Madhu's Xll class marks = 86

Difference = Xll - X = 86 - 76 = 10
