Question Numbers: 153-155

Directions: The following questions are based on the information given below. Analyze the data carefully to answer the questions.

There are three mi×tures A, B, and C, each consisting of only milk and water. The ratio of the total quantity of mi×tures P, Q, and R is given by p:q:r

The table below shows the partial composition of these mi×tures.

Mi×ture	Milk (Litres)	Water (Litres)
A	24	m
B	n - 4	20
C	3m	j

Notes:

(i) m and n are positive integers such that m +

n = 58

(ii) pn - qm = 16p

(iii) p and q are single-digit positive integers, both are less than 5, and q > p.

Question : 154 of 155

Marks: +1, -0

Solution:

Concept:

The total quantity of a mixture changes only by the amount removed or added, regardless of the composition of the mixture.

Explanation:

From the decoded values, the initial total quantity of mixture A is

42

When

21

L of the mixture is removed, the remaining quantity is:

42 - 21 = 21 \text{ L}

Then

19

L of pure water is added, so the new total quantity becomes:

21 + 19 = 40 \text{ L}

Thus, after removing and adding, the new total quantity of mixture A is

40

Answer:

40

L (Option C).
