6 men can repair a road in 14 hours. How many men are required to repair the road in 4 hours?
Answer & explanation
Correct answer: option 1
Formula to be used here,
\( { M}_{1 } \) x \( { H}_{1 } \) = \( { M}_{2 } \) x \( { H}_{2 } \)
where, M = No. of Men, H = No. of Hours,
⇒ Putting in the values,
⇒ 6 x 14 = \( { M}_{2 } \) x 4
⇒ \( { M}_{2 } \) = 21.
