Let the Oranges be 'O', Bananas be 'B' and Apples be 'A'
From the given data,
2O + 3B + 4A = 15 ...... (I)
3O + 2B + A = 10 ..... (II)
On adding (I) and (II),
5O + 5B + 5A = 25
O + B + A = 5
4O + 4B + 4A = 20.
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
