Here, A will have to cover a distance of (500 ? 140) = 360 meters to reach the winning point while B 500 meters . A covers 3 while B covers 4.
? A covers 360 m while B covers 4 x 360/ 3 = 480 m
Hence, B will be (500 ? 480) = 20 m behind the winning post.
? A wins by 20 m.
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
