Question

11 men can dig 6 m long trench in one day how many men should be employed for digging a 27 M long trench of the same type in one day

Answer 1

$\Italics{We\:will\: use\:CHAIN\: RULE\:to\: solve\: this.}$

Note: According to Chain Rule, the work efficiency remains same.

Let, ‘W’ work is done in both the cases. So, using CHAIN RULE,

6/(11*1) = 27/(x*1)

where, x is the number of men required to complete the work.

Or, x=(27×11)/6

Or, x=49.5Menx (Answer)

But we can't have 49.5 Men, so we will need 50 Men to complete the required work in one day.
