Let maximum marks be N .
According to the question,
75N/100 - 70 = 112 - 32
? 75N/100 = 80 + 70
? 75N/100 = 150
? N = 200
Passing marks = 112 - 32 = 80
(as Rajesh got 112 marks which is 32 more than the passing marks)
? Minimum passing marks percentage
= (80/200) x 100%
= 40%
The shaded region represents
y ? x
Let 45 x A = (25 x 900)/100
? A = (25 x 9)/45 = 5
CP = [100/(100 - Loss%) ] x SP
CP = 6000 x (100/75) = 8000
NA
Angle swept in 30 min= 180°
Area swept = [(22/7) x 7 x 7] x [180°/360°] cm2
= 77 cm2
