**Answer:**

** 5.688%**

**Explanation:**

Given that

Purchase securities = $3,750,000

Sale value of securities = $3,780,000

Number of days given = 50 days

So, the formula to compute the repo rate is shown below:

Yield or repo rate is

**= (Sale value of securities - purchase price) ÷ (Sale value of securities) × 360 days ÷ 50 days **

= ($3,780,000 - $3,750,000) ÷($3,780,000) × 360 days ÷ 50 days

= 0.0079 × 7.2

=** 5.688%**

W\e assume the 360 days in a year
