Explanation
A's 1 day's work = | 1 | ; |
15 |
B's 1 day's work = | 1 | ; |
20 |
(A + B)'s 1 day's work = | ❨ | 1 | + | 1 | ❩ | = | 7 | . |
15 | 20 | 60 |
(A + B)'s 4 day's work = | ❨ | 7 | x 4 | ❩ | = | 7 | . |
60 | 15 |
Therefore, Remaining work = | ❨ | 1 - | 7 | ❩ | = | 8 | . |
15 | 15 |
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
