Question

45. 12 men complete a work in 9 days. After they have worked for 6 days, 4 more men join them. How many days will they take to complete the remaining work ?

Answer 1

Step-by-step explanation:

12×9=12×6+(12+4)x

108=72+16x

16x=108-72

16x=36

x=36/16

x=9/4

remaining work complete in 2.25 days
