The correct option is B 600
No. of sweets boxes = 58
No. of sweets in each box = 12
Consider number 58, ones digit is 8 which is greater than 5.
So, while rounding off, ones digit will be replaced with 0 and tens digit will be increased by 1.
So, 58 will be rounded off to 60.
Similarly, consider number 12, ones digit is 2 which is less than 5.
Hence, ones digit will be replaced with 0 and tens digit will remain the same.
So, 12 will be rounded off to 10.
Estimated values:
Number of sweets boxes = 60
Number of sweets in each box = 10
Total number of sweets
=60×10=100
