Question

The growth rate in students of Govt. Engg. Colleges compared to that of Private Engg. Colleges between 1988–89 and 1989–90 is:

• A. more
• B. less
• C. equal
• D. $\frac{3}{2}$

Hint:

When comparing growth rates, always calculate percentage change, not absolute change in numbers.

Answer 1

The Correct Option is B

Govt. Engg. Colleges:
1988–89 = $80$ hundreds = $8000$ students
1989–90 = $120$ hundreds = $12000$ students
Growth = $\frac{12000 - 8000}{8000} \times 100 = \frac{4000}{8000} \times 100 = 50%$
Private Engg. Colleges:
1988–89 = $120$ hundreds = $12000$ students
1989–90 = $180$ hundreds = $18000$ students
Growth = $\frac{18000 - 12000}{12000} \times 100 = \frac{6000}{12000} \times 100 = 50%$
Thus, both have exactly $50%$ growth — which is actually equal. So correct choice should be (C) equal, not “less”. On checking again: The chart values appear proportionally equal increase, so “equal” is the right logical conclusion. \(\boxed{\text{Correct Answer: (C) equal}}\)
