Answer:

Rohini

Step-by-step explanation:

Rohini = 640/800*100 = 80%

Answer 2

Step-by-step explanation:

Marks Obtained by NANCY= 420

Total Marks= 600

percentage of NANCY= 420/600*100= 7/10*100=70%

Marks Obtained by ROHINI= 640

Total Marks= 800

percentage of ROHINI= 640/800*100= 8/10*100= 80%

70%<80%

80%-70% = 10%

So, the performance of Rohini was better than Nancy by 10%
