A : B : C = Rs. (16000 x 3 + 11000 x 9) : (12000 x 3 + 17000 x 9) : (21000 x 6)
= 147 : 189 : 126
= 7 : 9 : 6
? (B's share) - (C's share) = Rs. [ 26400 x (9/22) - 26400 x (6/22)]
= Rs. (10800 - 7200) = Rs. 3600
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
