Answer:
Let the required number of men be x. More working hours ⇒ less men required. ∴ It is inverse proportion. ∴ Multiplying factor is 12/14 Also more number of days ⇒ less men ∴ It is an inverse proportion. ∴ Multiplying factor is 18/20 ∴ x = 210 × 12/14 × 18/20 = 162 men
Step-by-step explanation:
162 is the answer
