### Answers and Explanations

**Answer 1. (d)**

Total investment in the two districts in year 2001 = 2932.1+7081.6 ≈ 10,000

Total investment in the two districts in year 2002 = 3489.5+ 8352 ≈ 11840

Required percentage = (11840 – 10000)/10000 = 18%(approx.)

**Answer 2. (b)**

From the given data we know that,

Total investment in electricity and chemical energy in both the districts in 2001 = (815.2 + 632.4 + 2065.8 + 1232.7) = 4746.1

Total investment made in that year = 2923.1 + 7081.6 = 10004.7 ≈ 10000

∴required percentage = (4746.1/10000) = 47% (approx.)

**Answer 3. (b)**

Percentage increase in investment in electricity = 300×100/2070 = 14%

Percentage increase in investment in thermal= {(986.4 – 745.3)/745.31} x 100 = 240/745 = 32%

Percentage increase in investment in solar

= (428.6×100/1363.5) let’s take the approximate values = 430/1360 = 31.5%

And the Percentage increase in investment in nuclear

= 507/1674 approximately = (500/1670)x 100 = 30%

So, clearly percentage increase in investment in thermal is the highest

**Answer 4. (c)**

Total investment in Ludhiana = 2923.1 + 3489.5 = 6412.6 ≈ 6410.

Total investment in Jalandhar = 7081.6 + 8352 ≈ 15430.

∴Required ratio = (15430/6410) = 2.4 times
