Jason pays 7 1/2 of his salary in tax. His deduction are K20 insurance, K50 savings and loans and K50 for superannuation savings. If His salary per fortnight is K1 329.40, what amount would be?

First, we need to calculate Jason's total deductions:

K20 (insurance) + K50 (savings and loans) + K50 (superannuation savings) = K120

Next, we need to calculate how much of Jason's salary goes towards taxes:

7 1/2% of K1 329.40 = 0.075 x K1 329.40 = K99.705

Now, we can calculate Jason's net salary after deductions and taxes:

K1 329.40 - K120 (deductions) - K99.705 (taxes) = K1 109.695

Therefore, Jason's net salary per fortnight would be K1 109.695.

Step 1: Calculate the amount of tax Jason pays.

7 1/2 of K1,329.40 = (7/2) - K1,329.40 = K5,317.60

Step 2: Calculate the total deductions.

K20 + K50 + K50 = K120

Step 3: Calculate the net salary.

Net salary = Gross salary - Tax - Deductions
Net salary = K1,329.40 - K5,317.60 - K120
Net salary = K4,891.80

Therefore, Jason's net salary would be K4,891.80.
