The sale of electric bulbs on different days of a week is given in the table. Observe the pictograph and answer the following questions:
a) How many bulbs were sold on Friday?
From the pictograph given on the slide,
Friday has 7 symbols.
It’s given that one symbol represents 2 Bulbs.
So, 7 symbols = 2 × 7 = 14 Bulbs
Thus, on Friday 14 bulbs were sold.
