(1.00) x + (0.20) x = 240
(1.20) x = 240
x = 240 / 1.2
x = 200
If you increase it by 10% and then reduce it by 10% you don't get the original number. Example 100 + 10% = 110. However if you now take 10% of 110 away that is 11. And 110 minus 11 = 99.
...so the number is 10 less than 16. Can you work it out now...?
123 percent can be written as 1.23. Now multiply that by 150 and you have 184.5. In general, to do this take the percent and move the decimal over to the left 2 places then multiply by that number.
One way to do this is multiply 8x3=24 so 24 has both as factors. Now multiply it by 10 and you have 240. That is a 3 digit number and sill has 8 and3 as factors.
First find what 73% of 350 is. 73% of 350 is 255.5. Now find 25% of 255.5. 25% of 255.5 is 63.875. 63.875 is 25% of 73% when the total is 350.
If you increase it by 10% and then reduce it by 10% you don't get the original number. Example 100 + 10% = 110. However if you now take 10% of 110 away that is 11. And 110 minus 11 = 99.
Call the number we seek x, now we have .1x+x=352 or x(1.1)=352 so x=352/1.1
Firstly, convert 125% to a decimal: you can do this by dividing by 100 to get:125 / 100 = 1.25Next, multiply this decimal by your number you want to find the percentage of:1.25 x 240 = 300So, your answer is 300Another method is this way:Firstly work out 100%. This is 240.Now, to find 125% you need an extra 25% (because you already know 100%)25% is equivalent to one quarter so you can find this by dividing 240 by 4 to get:240 / 4 = 60So, now you know 100% and 25% so you can simply add these values together to give your answer:240 + 60 = 300
The cost increased by 231.05%
The greatest common factor is a function of two numbers-- it is the greatest factor that the numbers have in common. The concept does not apply to a single number. Now you can use the same number twice and ask what is the greatest common factor of 240 and 240 and the answer would be 240.
Your money increased by 50%
The bond's value increased by 35%
...so the number is 10 less than 16. Can you work it out now...?
Set original income to be x and expenses were 0.75x, so he was saving 0.25 Income is now (1+ .2)x=1.2x and expenses are now (1 + .1)(.75)=0.825 savings are now 1.2-0.825=0.375, and .375/.25 = 1.5 so this is a 50% gain in savings.
The formula for percent work efficiency is: percent efficiency = (work output/work input) x 100 To find the answer to this question, you just need to plug the given values into the formula. The problem tells you that the work input is 240 J and the percent efficiency is 75 %, so 75 = (work output/240) x 100 Now, solve for work output: -first divide by 100 .75 = (work output/240) -then multiply by 240 180 J = work output (in units of joules because work is measured in joules) And there's your answer. Hope this helped!
No. For example, 500 increased by 10% = 550 Now, decreasing 550 by 10% results in: 495, not 500.
25% of 60 = 15 OR if you are saying, it now costs $60 and it is 25% of the original price, then the original price = $240.
