Explanation / Answer

Q.17 Percent of lawn covered by bag of fertiliser = 3600 * 100/ 48000 = 7.5%

Q.18 Total number of nurses = 40/40 * 100 = 100 Nurses

Q.19 Total price = 72 * (1 + 6.4/100) = $ 76.608

Q.20 Increase in salary = $ 52800 * 5.2/100 = $ 2745.6

Q.21 Sales price = $ 3300 * (1 - 25/100) = $ 2475

Q.22 Commission rate = 24000 * 100/ 2000000 = 1.2%

Q.23 Sales Tax rate = 2.28 * 100/24 = 9.5%

Q.24

Final value = P * R * T/100 = 12000 * 3 * 6/100 = $ 2160

Total Loan amount = 12000 + 2160 = $ 14160

Q.25

Here final amount = 10000 * 4.00639 = $ 40063.9

Interest = 40063.9 - 10000 = $30063.9
