(a) Cost of 5 kg of wheat = Rs.30.50 

Cost of 1 kg of wheat = 30.50/5 = 3050/500  = Rs.6.10 

Cost of 8 kg of wheat = 6.10 x 8 = Rs.48.80 

(b) From Rs.30.50, quantity of wheat can be purchased = 5 kg 

From Rs.1, quantity of wheat can be purchased = 5/ 30.50 

From Rs.61, quantity of wheat can be purchased = 5/30.50 x 61 = 5/3050 x 6100 = 10 kg
