Best answer
Correct Answer - Option 4 : 1 ∶ 12

Given:

Number of total men = 3

Number of days = 18 days

Per day work = 8 hours

Formula:

Work = Men × days × hours

Calculation:

Work = men × hours × days = 3 × 18 × 8

New Work = 2 × 2 × 9

Required ratio = (2 × 2 × 9)/( 3 × 18 × 8) = 1/12

Required ratio is 1/12
