Let respective weights of Shubha, Govinda and Reshma is $$s , g , r$$ kg Average weight of the three = $$frac{s + g + r}{3} = 65$$ => $$s + g + r = 65 imes 3 = 195$$ kg --------------(i) Similarly, Total weight of Shubha and Govinda = $$s + g = 63 imes 2 = 126$$ kg ---------------(ii) Total weight of Govinda and Reshma = $$g + r = 70 imes 2 = 140$$ kg -------------(iii) Adding equations(ii) and (iii), => $$s + 2g + r = 126 + 140 = 266$$ ---------------(iv) Subtracting equation (i) from (iv), we get : => $$g = 266 - 195 = 71$$ kg => Ans - (B)
