    Answer : Option A

    Explanation :

    5 men colour 50-meter long cloth in 5 days.

    1 man will colourApti Time and work 63= 10-meter long cloth in five days.

    So, in one day one man can colourApti Time and work 64= 2-meter long cloth.

    Now, as per question 4 men are supposed to colour the 40-meter long cloth.

    One man has to colour the Apti Time and work 65= 10 meter cloth

    For 2-meter long cloth one man takes 1 day

    So, to paint 10-meter long cloth he will take =Apti Time and work 66

    As, 4 men are working together so 40 m long cloth will be coloured in 5 days

    Quicker method:

    Apply formula: M1D1W2 = M2D2W1

    5*5*40 = 4*D2*50

    D2=Apti Time and work 67
