Answer 1

Answer:

123,400 pharmacists.

Step-by-step explanation:

Let the Number of pharmacists in 1980 be x.

Percentage increase in number of pharmacists = 89% of x

Number of pharmacists in year 2018 = $x + \frac{89x}{100}= \frac{189}{100}x$

According to question,

$\frac{189}{100} x = 2,33,226$

$x = \frac{233226}{189} \times 100 = 123400$

Therefore, the number of pharmacists in 1980 were 123,400.
