Correct answer: 2/3
We can count the total number of squares/cells in the grid and then deduct the number of blacked-out cells.
The total number of cells is 6.
Amount of cells Not covered in black: (3 whole cells + 2 half-cells)=4
4/6=2/3
Correct answer: 0.55 m
Find the'middle' number by counting the number of birds in the chart.
To get the median, multiply the number of birds by one and divide by 2 to get the middle value.
The median wingspan is 12 + 1 = 13 / 2 = 6.5 since there are 12 birds.
As a result, the median is located halfway between the 6th and 7th numbers.
The sixth is at 0.50m and the seventh is at 0.60m. 0.55 Is halfway between these.
Correct answer: 8

Correct answer: £10,000
Determine when the most significant price change occurs:
Between 10:00 and 11:00 a.m., this occurs.
The change is 176p to 174p – 2p.
Determine how this affects the company's worth.
The corporation has a total of 500,000 shares, so:
0.02 x 500,000 = £10,000 – C.
Correct answer: 2.8 m/s
Calculate the average speed by converting the units to metres and seconds.
1 hour = 60 minutes = 60 x 60 seconds = 3600 s
10 km = 10,000 m
So in metres per second:
10000 / 3600 = 2.777… = 2.8 m/s
Correct answer: 67.80%
Calculate the percentage of coffee beans used in cafés as a percentage of total coffee beans used.
Beans in cafés: 242,000
Beans in total: 242000 + 50300 + 28341 + 36324 = 356965
242000/356965 = 0.6779… = 69.8%
Correct answer: He pays £125 less
Calculate his rent over the years.
He paid 75% of the market average (£1000 PCM at the time).
0.75 x 1000 = 750
The average price went up from 1000 to 1250
Use the following formula to calculate the percentage increase:
New Value / Old Value = Multiplier
1250/1000 = 1.25 = 25%
His rent jumped by double the rate, or by 50%.
For a percentage increase, use the following formula:
New value = Old value x multiplier
50% increase = multiplier of 1.5
New rent = 750 x 1.5
New rent = £1125
Calculate the difference from the market rent.
According to the graph, the new average rent is £1250.
£1250 – £1125 = £125 so he pays £125 below the market rate.
Correct answer: 21 to 30 miles
The majority of the stores (26) are located between 21 and 30 kilometers from the center.
Correct answer: $239,250
Calculate the monthly average by adding the incomes:
(120 + 145 + 130 + 15 +17.5 19 + 80 + 90 + 101) x 1000 = $717,500
To calculate the monthly average, multiply this by three.
$717,500/3 = $239,166… = $239,250 to the nearest $250.
Correct answer: 0.675 g
The percentage of copper in Coin A is (100 – 25) = 75%.
The amount of copper in Coin A, which weighs 6.5 g, is 6.5 75/100 = 4.875 g.
The amount of copper in Coin B is 100 – 16 = 84%.
The amount of copper in Coin B, which weighs 5 g, is 5 84/100 = 4.2 g.
The difference in copper content between Coin B and Coin A is 4.875 - 4.2 = 0.675 g.
Correct answer: 940 °C
480 + (480 – 20) = 940.
