15 men can complete a task in 10 days. In how many days can 20 men complete the same task? |
6.5 days 7.5 days 5.5 days 8.5 days |
7.5 days |
Formula to be used here, \( { M}_{1 } \) x \( { D}_{1 } \) = \( { M}_{2 } \) x \( { D}_{2 } \) where, M = No. of Men, D = No. of Days, ⇒ Putting values in the formula, ⇒ 15 x 10 = 20 x \( { D}_{2 } \) ⇒ \( { D}_{2 } \) = 7.5 days. |
