Answer 2

Answer:

6)cost of the pen=₹83/5

cost of the pencil=₹19/4

now we have to equivalent the denominator

83/5 and 19/4

83×4/5×4 and 19×5/4×5

332/20 and 95/20

332/20>95/20

therefore, cost of the pen is more than the cost of the pencil by ₹237/20

7)cost of 7.5kg of rice=₹262.5

cost of 1kg of rice=x

x=262.5/7.5=35

therefore, the cost of 1kg of rice=₹35
