​

Answer 1

Answer:

Rs.99

Step-by-step explanation:

4/5 metres = Rs.36

11/5 metres = x

By cross multiplication we get,

4/5 * x = 36 * 11/5

4/5x = 396/5

x = 396/5 * 5/4

Both the 5's cancel we get,

x = 396/4

x = 99

Answer 2

Step-by-step explanation:

4/5 = 0.20 and

Hence , 0.20 metre cloth costs ₹36

We know that ,

21/5 = 4.20

4.20 metre costs 21 ×36 = ₹756 ans
