Answer: Option C

Explanation:

P+Q+R = 90 tk

Q = 10+P

R = 2Q = 2(10+P) = 20+2P

P+Q+R = 90

P+10+P+20+2P = 90

P = 15

So, Q = 10+P = 10+15 = 25

Now, P+Q = 15+25 = 40

Average of P and Q is = 40/2 = 20 (Ans)

Answer: Option B

Explanation:

Let x g be the weight of solution X in 100 g of the mixture.
Then, the weight of solution Y in 100 g of the mixture = (100 - x) g

Mass of salt in the mixture:
x (40%) + (100 - x) (25%) = 100 (30%)
40x + 2500 - 25x = 3000
15x = 500
x = 33 1/3

Hence, there are (33 1/3)% of solution X in the mixture.

Answer: Option B

Explanation:

Let's denote the present ages of the husband, wife, and child as H, W, and C, respectively.

According to the given information:

Four years ago, the average age of the husband, wife, and child was 27 years. So, (H - 4 + W - 4 + C - 4) / 3 = 27.

Five years ago, the average age of the wife and child was 20 years. So, (W - 5 + C - 5) / 2 = 20.

We can simplify these equations:

1. (H + W + C - 12) / 3 = 27.

2. (W + C - 10) / 2 = 20.

Now, let's solve this system of equations:

From equation 2, we can express W + C as 2 * 20 + 10 = 50.

Substitute this value into equation 1:

(H + 50 - 12) / 3 = 27.

H + 38 = 81.

H = 81 - 38.

H = 43.

So, the present age of the husband is 43 years.
