The average weight of A, B , C and D is 67 kg.When a fifth man E joins then the average weight is reduced by 2 kg. A is replaced by F whose weight i more than E's by 4 kg. This brought down the average weight to 64 kg. The weight of A is
(a) 68 kg
(b) 73 kg
(c) 72 Kg
(d) 55 kg
Ans 8. weight of A + B + C + D = ( 4 x 67) kg
=268 kg
Weight of A + B + C + D + E = ( 5 x 65 ) kg
= 325 kg
Weight of E = 325- 268 = 57 kg
Weight of F = 57 + 4 = 61 kg
Weight of B + C + D + F = ( 4 x 64)
= 256kg
or Weight of B + C + D = 256-61
= 195 kg
. . Weight of A = 268- 195 = 73 kg
