Question Numbers (47 to 50): Answer the questions
on the basis of the information given below.
A large store has only three departments, Clothing,
Produce, and Electronics. The following figure shows
the percentages of revenue and cost from the three
departments for the years 2016, 2017 and 2018. The
dotted lines depict percentage levels. So for example, in
2016, 50% of store's revenue came from its Electronics
department while 40% of its costs were incurred in the
Produce department.

In this setup, Profit is computed as (Revenue – Cost)
and Percentage Profit as Profit/Cost × 100%.
It is known that
1. The percentage profit for the store in 2016 was 100%.
2. The store’s revenue doubled from 2016 to 2017, and
its cost doubled from 2016 to 2018.
3. There was no profit from the Electronics department
in 2017.
4. In 2018, the revenue from the Clothing department
was the same as the cost incurred in the Produce
department.
What percentage of the total profits for the store in
2016 was from the Electronics department?
