Total number of outcomes = 10c4 = 210
Favourable number of outcomes = 3c2 x 2c2 = 3 x 1 = 3
? Required probability = 3/210 = 1/70
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
