Total Questions= 15
1. Bharti attempted questions= 15
Answered correct= 9
Therefore marks for nine questions = 9*4= 36. But there is negative marking for every incorrect question two marks are reduced therefore question is incorrect =15-9 = 6
Marks reduced 6*2 = 12
Therefore total score 36-12= 24
*Her total score is 24/60 (ans)*
2. Questions attempted by Hema =5
Total questions answered correct = 5
Therefore marks received = 5*4 = 20
But due to negative marking marks lost = 2*10= 20
Therefore total marks = 20-20= 0
*Therefore total score of Hema =00/60*
