A ship has sufficient food to supply 600 passengers for 3 week. So how long would the food last for 900 people

Answer 1

To solve this problem, we can set up a proportion based on the number of passengers.

Let x be the number of weeks the food will last for 900 people.

According to the given information, we can write the following proportion:

600 passengers / 3 weeks = 900 passengers / x weeks

To solve for x, we can cross-multiply and then solve for x:

600 * x = 3 * 900
600x = 2700
x = 2700 / 600
x = 4.5

Therefore, the food will last for 900 people for 4.5 weeks.

Answer 2

The length of A,B and C are in the. Ratio 2:5:3. If the length of c is 9vmetres, find the length of A and B

Answer 3

Let's denote the length of A as 2x, the length of B as 5x, and the length of C as 3x. We are given that the length of C is 9 meters, so we can set up the equation:

3x = 9

Solving for x:

x = 9/3
x = 3

Now we can find the length of A and B:

Length of A = 2x = 2 * 3 = 6 meters

Length of B = 5x = 5 * 3 = 15 meters

Therefore, the length of A is 6 meters and the length of B is 15 meters.
