A work can be completed by 8 boys in 48 days. If 2 boys leave after working for 24 days, then how many days will be needed to complete the remaining work?
Answer & explanation
Correct answer: option 3
Formula to be used :
⇒ \( { M}_{1 } \) x \( { D}_{1 } \) = \( { M}_{2 } \) x \( { D}_{2 } \)
where, M = N. of men, D = No. of days,
⇒ Putting values in the formula;
⇒ 8 x 24 = 6 x \( { D}_{2 } \)
⇒ \( { D}_{2 } \) = 32 days.
