21. On the scale of 1unit length = 10 crore, the bar of length 6 units will represent ________ crore and of units will represent 75 crore.
Solution:
From the question it is given that, 1 â€“ unit length = 10 crore,
So, bar of length 6 unit = 6 Ã— 10
= 60 crore
Then, number of units will represent 75 crore = 75/10
= 7.5 units
On the scale of 1unit length = 10 crore, the bar of length 6 units will represent 60 crore and of 7.5 units will represent 75 crore.
