4. On a scale where 1 unit length equals 10 crore, the bar with a length of 6 units will be comparable to 75 crore.
4. On a scale where 1 unit length equals 10 crore, the bar with a length of 6 units will be comparable to 75 crore.
Explanation:
The answer to the question is 10 crore divided by 1 unit of length.
Hence, a bar of length 6 units equals 6 10.
= 60 crore
Hence, the number of units will equal 75 crore, or 75/10.
= 7.5 units
5. On a scale where 1 unit length equals 10 crore, the bar with a length of 6 units will represent 60 crore, while one with a length of 7.5 units will represent 75 crore.
The following table lists the exam results for 30 students in a class. Use tally marks to arrange the following grades in a table: B, C, C, E, A, C, B, B, D, D, D, B, C, C, C, B, E, C, B, E, C, D.
