Martin earns K45,210 per annum. His employer pays 15% superannuation on his behalf and Martin pays 6%. How much superannuation does the employer pay on behalf of Martin per year?

Martin's salary per year is K45,210.

Martin's employer pays 15% superannuation on his behalf.

That means Martin's employer pays 15/100 * K45,210 = K<<15210=15600>>15,600 per year on behalf of Martin. Answer: \boxed{15,600}.

To calculate the employer's superannuation contribution for Martin, we need to find 15% of his annual salary.

Step 1: Calculate the employer's superannuation contribution.
Employer's superannuation contribution = 15% of Martin's annual salary.

Given that Martin earns K45,210 per annum, we can calculate the employer's superannuation contribution as follows:

Employer's superannuation contribution = 15/100 * K45,210

Step 2: Calculate the employer's superannuation contribution.
Employer's superannuation contribution = 0.15 * K45,210

Using a calculator, we can calculate this value:

Employer's superannuation contribution = K6,781.50 per year.

Therefore, the employer pays K6,781.50 on behalf of Martin each year as superannuation contribution.
