Problem in calculating outsourcing cost

Hi All! I have successfully been able to solve Q1 for Option A after weeks of trying! It was so confusing but I will list the method below to help!

Step 1) Calculate the salaries. Complete the sum of:
Head of Accounts = salary is unchanged
FQ = (2 x FQ cost) * 1.10
PQ = (3 x PQ cost) * 1.10
AT = (4 x AT cost) *1.10
= Total all of the above to get the TOTAL SALARY COST.

Step 2) Calculate 25% of the TOTAL SALARY COST.

Step 3) Sum the below for other costs. Note: these are unchanged so take the amounts as listed.
Amortisation + Accounting admin costs = TOTAL OTHER COSTS.

Step 4) Total everything to get your final answer:
S1) TOTAL SALARY COST X
S2) TOTAL SALARY COST * 25% X
S) TOTAL OTHER COSTS X
TOTAL = ANSWER

Hope this helps you guys! You only need 50% to pass so if you use the above for Q1, leave Q2 blank if you cannot calculate and then Q3 is multiple choice so is straightforward.

I did not understand your steps. You mentioned “Step 3) Sum the below for other costs. Note: these are unchanged so take the amounts as listed.
Amortisation + Accounting admin costs”

This should be as follows: (10% * 80) + (20%*160)

Furthermore the final calculation:

Step 4) Total everything to get your final answer:
S1) TOTAL SALARY COST X
S2) TOTAL SALARY COST * 25% X
S) TOTAL OTHER COSTS X
TOTAL = ANSWER

do we need to multiply Step 1 * Step 2 * Step 3? Please. Thank you

I am still unable to solve please can you elaborate more?
