Question

13. 15 men can build a 16.25-m-long wall up to a certain height in one day.how many men should be employed to build A wall ofthe same height but of length 26 meter is one day ?​

Answer 1

Answer:

24 mens

Step-by-step explanation:

I WILL SOLVE IT ACCORDING TO PROPORTION MEATHOD

no. of men who can build 16.25m long wall=15

no. of men who can build 26m long wall =x

it is in direct proportion as we increase the length of wall it needs more men to complete the work in 1 day

so 16.25:15::26:x

product of means =product of extremes

16.25x=15×26

x=

$\frac{15 \times 26}{16.25} \\ = \frac{15 \times 26 \times 100}{1 625} = 24$

x=24

so it requires 24 men's to make a 26 m long wall in 1 day
