Question

20 men can build a 112 M long wall in 6 day what will be the length of a similar wall that can be built by 25 men in 3 days

Answer 1

20 men × 6 days = 112m long
120 = 112m long
1 men 1 day= 112/120
1 men 1 day= 0.933 m long (approx)

25 men × 3 days
=> (25×3) × 0.933
=> 75 × 0.933
=> 69.975 m long

The length of wall built using 25 men in 6 days is => 70m long

Answer 2

20 men x 6days =112 m long
120=112m long
1man can do in one day =>112/120=0.933m long
25 men in 3 days =>25 x 3 =75
=>75 x 0.933
=69.975m long
The length of wall using 25 men in 3 days is 70m long.
