Question

Three friends distributed their total property. The ratio of total property, share of first friend and share of second friend is 24 : 7 : 8. Find the central angle of sector, which represents the share of the third friend. A  B 135º C 105º D 

Answer 1

The share of the third person = 24 - (7+8) = 9

Central angle of sector = $\frac{9}{24}$ × 360° = 135°

Answer 2

share of 3rd person =24-(7+8)
                                 =24-15
                                 =9
central angle=9/24*360
                    =135
