Explanation

The dial of a standard telephone has numbers 0 through 9.

The product of all these numbers is:

0 × 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 = 0

Since any number multiplied by 0 is 0, the product is 0.

Explanation

Let's denote Akram's age as 10a + b and his wife's age as 10b + a, where a > b.

Given the difference between their ages is 1/11 of their sum:

(10a + b) - (10b + a) = 1/11 * ((10a + b) + (10b + a))

9a - 9b = 1/11 * (11a + 11b)

9(a - b) = a + b

9a - 9b = a + b

8a = 10b

4a = 5b

Possible values for (a, b) given a > b:

(5, 4)

Akram's age: 10_5 + 4 = 54

Wife's age: 10_4 + 5 = 45

Explanation

The heart is the central organ of the blood circulatory system, responsible for pumping blood throughout the body.

It circulates oxygen, nutrients, and waste products via arteries and veins.

Explanation

Direct Speech: "Shall I ever go there again?" he asked.

Indirect Speech: The question is yes/no type, so it changes using "whether" or "if".

"Shall I" becomes "he would" (future in past).

Pronoun "I" → "he"

Hence, the correct transformation is:

He asked whether he would go there again.

Explanation

Let's calculate the amount Aslam borrowed:

Cost of cow = Rs. 82000

Aslam borrowed 55% of the cost:

Amount borrowed = 55% of 82000

= 0.55 × 82000

= Rs. 45100

Explanation

Given:

5y > 35

2y < 20

Solving the inequalities:

5y > 35 → y > 7

2y < 20 → y < 10

Since y is an even integer and 7 < y < 10, the only even integer in this range is 8.

Aluminum is widely used in aircraft manufacturing due to its lightweight and high strength.

It also resists corrosion, making it ideal for aircraft structures.

Explanation

Let's denote the amount of rice Aslam gets as x.

Akram gets twice as much as Aslam: 2x

Akbar gets half as much as Akram: (1/2)(2x) = x

The total amount of rice is 480 kg, so:

x + 2x + x = 480

4x = 480

x = 120

Akram gets 2x = 2(120) = 240 kg
