Question

11 men can dig 643​ metre long trench in one day. How many men should be employed for digging 27 metre long trench of the same type in one day?

​

Answer 1

Answer:

We will use CHAIN RULE to solve this.

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

i.e. WORK DONEWORKFORCE×TIME=CONSTANT

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

611×1=27x×1

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

Or, x =(27×11)6

Or, x=49.5Men (Answer)

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