Answer 2

Given:

if 8 labours can construct 1 wall in 12 hours

To Find:

find the time required by 32 labours to construct the same wall​

Solution:

It is given that 8 labours can construct 1 wall in 12 hours and we need to find the time required by 32 labours to construct the same wall​

To find the answer to this question we will use the formula for Time and work which states,

$\frac{M_1D_1H_1}{W_1} =\frac{M_2D_2H_2}{W_2}$

where,

        M= manpower

        D= days

        H= hours

        W= work done

So now putting the values of each in the formula and taking the value of time required as x,

$\frac{8*12}{1} =\frac{32*x}{1} \\x=3 hours$

Hence, the time required to construct the same wall by 32 labours is 3 hours.
