CorrectNot quiteAnswer B

Correct answer: B

Sports: 10%. Library: 8%. Difference: 2% of the spending.
$0.02 \times 80{,}00{,}000 = 1{,}60{,}000$ , that is ₹1,60,000.

Worth noting

Subtract the percentages first; one multiplication is faster than two. ₹8,00,000 is the sports spending itself. ₹6,40,000 is the library spending itself. ₹16,000 slips a decimal place: 2% is 0.02.
