Answer 1

Answer:

(a)0.5 kg, (b)75 people

Explanation:

Amount of food (w) is inversely proportional to number of people (N)

So,

w = k/N (where k is constant)

wN = k

From above relation we can write

w1N1 = w2N2

a)

w1N1 = w2N2

1.2 kg × 25 = w2 × 60

w2 = (1.2 kg × 25)/60

w2 = 0.5 kg

b)

w1N1 = w2N2

1.2 kg × 25 = 0.4 kg × N2

N2 = (1.2 kg × 25)/(0.4 kg)

N2 = 75
