12 men can weave 20 shawls in 9 days. How many men will be required to weave 25 shawls in 27 days?
Answer & explanation
Correct answer: option 2
Formula to be used here,
⇒ \(\frac{M_1\;×\;D_1}{M_2\;×\;D_2}\) = \(\frac{W_1}{W_2}\),
where, M = No. of Men, D = No. of Days, W = Work,
⇒ Putting values in the formula,
⇒ \(\frac{12\;×\;9}{M_2\;×\;27}\) = \(\frac{20}{25}\),
⇒ \( { M}_{2 } \) = 5.
