Time and Work

There was some food in the store which would have been sufficient for a certain number of men for 100 days. However, after 25 days 8 more men joined the group because of which the food lasted only for 35 more days. How many men were there in the group initially?

  1. EMDH/W = constant

    E.. efficiency
    M…no of men or workers
    D… days
    H… hours per day
    W… amount of work

    Here answer is 7

  2. 7men
    quantity/no.of men =days
    quantity=x, no.of men=y, x/y=100
    for first 25 days y consumed so x/4 consumed therefore
    3x/4 consumed by y+8 men in 35 days
    solving them answer is 7men

    let there are x men initial food = 100 x
    after 25 days food left 100 x-25x = 75 x
    75 x = 35 (x+8)
    solving x= 7
