1.	workIf 20 men can build a wall 112 meters long in 6 days, what length of a similar wall can bebuilt by 25 men in 3 days?- AT:
Answer» M1 * D1 / W1 = M2 * D2 / W2 M-> MEN , D-> DAY , W-> WORK therefore,M1=20;M2=25; D1=6; D2=3; W1=112;W2=? 20 * 6 / 112 = 25 * 3 / W2 120 / 112 = 75 / W2W2=(75×112)/120W2 = 70m Thus 25mens in 3 days can build a wall of 70m long

Answer»

M1 * D1 / W1 = M2 * D2 / W2

M-> MEN , D-> DAY , W-> WORK

therefore,M1=20;M2=25; D1=6; D2=3; W1=112;W2=?

20 * 6 / 112 = 25 * 3 / W2

120 / 112 = 75 / W2W2=(75×112)/120W2 = 70m

Thus 25mens in 3 days can build a wall of 70m long
