    Answer : Option B

    Explanation :

    Rate of consumption of each man = 1050/(150 * 30) = 7/30 kg/day
    Let us say 70 men take x days to consume 150 kg.
    Quantity consumed by each item in x days = 7x/30 kg.
    Quantity consumed by 70 men in x days = (7x/30)(70)kg
    (7x/30)(70) = 980
    x = (980 * 30)/490 => x = 60 days
