Answer 1

cost of 5kg of wheat is 30.50
cost of 1kg is 30.5 ÷5=6.5kg
cost of 8kg =8×6.5=52 rs

Answer 2

cost of 5K.G.=30.50rs.
(a)cost of 8K.G.=30.50÷5×8=48.8rs.
(b)wheat purchased in 61rs.=quantity×rate=quantity×30.50÷5
                                          61=quantity×6.1
                                          quantity=61÷6.1
                                      so,quantity=10K.G.
