Answer:
let the minimum score be 'x'
=> (28 + x)/80 = 80/100
=> (28+x)100 = 6400
=> 28+x = 64
=> x = 36
therefore, Snehal had to score minimum of 36 marks

Answer:
Let the minimum score be x.
(28+x)/80 = 80/100
(28+x)100 = 80×80
2800 + 100x = 6400
100x = 6400 - 2800
100x = 3600
x = 3600/100
x = 36
=> 36 marks
Step-by-step explanation:
