then 1m will cost =2160/4

= 54

so cloth material borrowed in 1620 rupees is = 1620/54

=30

so, 30m of cloth can be bought for rupees 1620

How many meters will cost Rs 1620?

Ratio of cloth = 40 : x

Ratio of cost = 2160 : 1620 = 216 : 162 = 108 : 81 = 4 : 3

Now, Cost of the cloth is directly proportional to the length of the cloth

40 : x = 4 : 3

4x = 120

x = 30

Cost of 30 metres cloth is Rs 1620
