Answer:

500 Students

Step-by-step explanation:

Let Total number of students = S

Passed in Science = 0.77 S

Failed in Science = S - 0.77S = 0.23S

Passed in Hindi = 0.66 S

Failed in Hindi = S -0.66S = 0.34S

Failed in Both = 0.13S

Total Failed in Any subject = 0.23S + 0.34S - 0.13S = 0.44S

Passed in both subject = S -0.44S = 0.56S

0.56S = 280

S = 280/0.56

S = 500
