Answer 2

Answer:

Answer Rs. 36.36

Solution :

Cost of 1 kg of A = Rs.30 = cheaper quantity.

Cost of 1 kg of B = Rs.40 = dearer quantity.

Let the mean price be Rs.X.

Applying the rule of alligation,

Therefore, (Cheaper quantity) : (Dearer quantity) = (d - m) : (m - c) = (40-X) : (X-30)

Given ratio = 4/7 = 40-X/X-30

280-7X = 4X - 120

11X = 400

X = 400/11 = 36.36

Hence, the required mean price is Rs.36.36
