Show answer & explanation
Correct answer: C
Concept
When the same percentage applies to several quantities, first add the quantities and then apply that common percentage. This uses the distributive rule: p% of (a + b + ...) equals p% of a plus p% of b plus ... .
Convert a percentage p% to p/100 before multiplying. Keeping the common percentage outside the sum reduces repeated arithmetic.
Application
Add the seven state investments: 3120 + 3560 + 3940 + 1380 + 1460 + 1660 + 3880 = 19000 crore rupees.
The share for the Others sector is 19.5%, so write it as 19.5/100.
Apply the percentage to the combined investment: 19000 × 19.5/100 = 190 × 19.5 = 3705 crore rupees.
Cross-check
Use 19.5% = 20% - 0.5%. Now 20% of 19000 is 3800 and 0.5% of 19000 is 95; therefore 3800 - 95 = 3705.
Therefore, the total foreign investment in the Others sector is 3705 crore rupees.
