40 men can build a wall 4 metres high in 15 days the number of men required to bulid a samilar wall 5 metres high in 6 days​

Answer 1

Answer:

40 men ,4 meter wall=15 days

Therefore,1 meter wall=40÷4=10 men

Therefore,5 meter wall=10×5=50 men

50 men 5 meter wall =15 days

1 day=50×15=750 men

6 day = 750÷6=125 men

Answer 2

The number of men would be 125.

Step-by-step explanation:

Since we have given that

Number of men = 40

Length of wall = 4 meter

Number of days = 15

If the length of wall = 5 meter

and number of days = 6

Then, we need to find the number of men:

So, Using "Time and work" we get that

$\dfrac{40\times 15}{4}=\dfrac{x\times 6}{5}\\\\150=\dfrac{6x}{5}\\\\750=6x\\\\x=\dfrac{750}{6}\\\\x=125$

Hence, the number of men would be 125.
