The following table shows the number of bundles of iron bars of 5 different brands sold from a shop during a given week.

The number of iron bars in each bundle of B1 and B3 is 5. The number of iron bars in each bundle of B2, B4 and B5 is 4. What is the total number of iron bars sold from the shop during that week of all the 5 brands taken together?

1100

Total number of iron bars sold from all the brands = 60×5 + 50×4 + 40×5 + 45×4 + 55×4

= 300 + 200 + 200 + 180 + 220

= 1100
