Question

15 man can build a 16.25 m long wall iup to a certain height 1n one day .how many men should be employed to build a wall of the same height but of length 26 mtrs in one day

Answer 1

Note: Use ratio and proportion in this question.

15 men:16.25 m wall in 1 day

Therefore,

x men:26 m wall in 1 day
(Note: x is a variable)

15 : 16.25 :: x : 26

You know that rule about product of
means=product of extremes?

Here,

15*26=16.25*x

=390=16.25*x

x=390/16.25=24

Therefore, it will take 24 men to build a 26 m high wall in one day.

Answer 2

15 men ----------------------------- 16.25m long----------------------------------1day

x men -------------------------------- 26 m long ------------------------------------1 day

15 men = 16.25

x men =26

cross multiply

26×15=16.25×x

390=16.25 × x

x=390/16.25

x=24

Hope this helps you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
