Speed of car = Distance/Time = 200/240/60
= 600/8 = 75 km/h
Speed of jeep = 200/2 = 100 km/h
? Required ratio = 75/100 = 3/4 3 : 4
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
