Ratio of investments of A, B & C = 2×6+4×6 : 3×12 : 4×12
= 36 : 36 : 48
= 6 : 6 : 8
But given that the annual profit of B is Rs. 3000
=> 6 ratio = 3000
Then for the total annual profit of partners is
20 ratio = 3000 x 20/6 = 10,000.
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
