CP / SP = 29x / 19x
loss % = 29x - 19x / 29x X 100 = 34.48 %
(To understand the concept assume CP of each article Rs 29 and SP of each article = Rs. 19)
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
