Correct Answer - Option 4 : 27 ∶ 59

**Given:**

Number of shirts in company C_{1} = 27

Number of shirts in company C_{2} = 33

Number of shirts in company C_{3} = 26

**Calculation:**

Sum of the shirts in C_{2} and C_{3} = 33 + 26 = 59

⇒ Number of shirts in company C_{1}/Sum of the shirts in C_{2} and C_{3} = 27/59

**∴ The ratio of the number of shirts of company C**_{1} to the total number of shirts of company C_{2} and C_{3} is 27 : 59.
