ANSWER
(a)COST OF WHEAT = 5 kg. 8kg
RATE OF WHEAT PER KG= 30.50 Rs x
IT IS AN DIRECT PROPORTION
Therefore, 5kg×x = 8kg × Rs 30.50
x = 8kg × rs 30.50 divided by 5kg
= 48.8
Therefore it will cost 48.8Rs for 8 kgs of wheat
(b) COST OF WHEAT = 5 kg. x
RATE OF WHEAT PER KG =30.50 Rs. 61rs
IT IS AN DIRECT PROPORTION
Therefore, 5kg×61 rs = x × Rs 30.50
