City buses have an average of 1400 daily riders. During a gas shortage, the average number was 1554. What percent did the averag

I am Lyosha [343]

Answer:

11%

Step-by-step explanation:

<em>Percentage increase = (New average- previous average)/previous average x 100</em>

<em>New average: 1554</em>

<em>Previous average: 1400</em>

Percentage increase = (1554-1400)/1400 x 100

Percentage increase = 154/1400 x 100

Percentage increase = 0.11 x 100

Percentage increase = 11%

Therefore, the average increased by 11%.

The children from a football club are put into rows in the sports hall.When out in rows of 9 children, there are 2 children left

Anettt [7]

Answer:

The least number of children in the football club is 38.

Step-by-step explanation:

If children put in rows of 9, left out children = 2

If children put in rows of 12, left out children = 2

We will find least number of children in football club by finding LCM of 9 and 12.

Multiples of 9 are: 9, 18, 27, 36, 45, 54, 63,...

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,...

As we can see here: The LCM of 9 and 12 is 36.

We are told that 2 children left over from putting them into 9 and 12 children per row. To find least number we will add 2 to 36.

Therefore, the least number of children in the football club is 38.

Answer:

For 360 km of distance , The cost of fare = Rs 112

The distance cover by rail = 900 km

The cost of 900 km = Rs 280

Let The cost of journey for 360 km = Rs x

So , ∵ For 900 km of distance , The cost of fare = Rs 280

∴ For 360 km of distance , The cost of fare = $\frac{280}{900}$ × 360

Or, For 360 km of distance , The cost of fare = 0.311 × 360

∴ For 360 km of distance , The cost of fare = Rs 112 Answer
