• C. $179
• D. None of these
• A. 68%
• B. 57%
• C. 78%
• D. Cannot be determined

Answer 1

The Correct Option is A

Increased Percentage = \(\frac{Increase}{Initial}×100\)
Quantity in year 2002-2003 (Final) = 4.5
Quantity in year 1998-1999(Initial) = 2.3
Increase Percentage = \(\frac{4.5-2.3}{2.3}\)
= \(\frac{2.2}{2.3}\)
= 95.65%
The correct option is (A)

Answer 2

Let the total exports from India be t.
5% of total exports = leather goods worth were exported from India
\(\frac{5}{100}×t\) = 224.10
from the above equation t,
t = $4482
The correct option is (A)

Answer 3

Assume the total exports in 1999-2000 as t.
For Manufacturing goods sector = \(\frac{77.6}{100}\) × t
for gems industry = \(\frac{16.6}{100}\) × \(\frac{77.6}{100}\) × t = 300
from the above two equation,
t = 2328.9
India’s exports in 2002-2003 were = 1.5 × 1960.78 = 3493.35
The value of the exports of ores and minerals in 2002-2003 (in millions) = \(\frac{3.6}{100}\) × 3493.36 = 125.76
The correct option is (B)

Answer 4

In the year 1998-99
Assume the India exports be t 
Manufacturing goods industry = \(\frac{73.6}{100}\) × t
Engineering goods industry = \(\frac{12.5}{100}\) × \(\frac{73.6}{100}\) × t = \(\frac{920t}{10000}\) 
In the year 2002-03 
India exports = 1.2t 
Manufacturing goods industry = \(\frac{77.4}{100} ×  1.2t\)
engineering goods industry = \(\frac{16.6}{100}\) × \(\frac{77.4}{100}\) ×1.2 t = \(\frac{1541.808t}{100}\)
Percentage increase in exports of Engineering goods industry  = \(\frac{1541.808 - 920}{920}\)
= 67.5% approx. 68%
The correct option is (A)
