Answer:
5.5%
Step-by-step explanation:
The absolute error: 34.5-32.7=1.8
Percentage error: Relative error * 100%
To get the relative error, you can calculate it by (absolute error)/(actual value) or (max error)/(measured value)
Since you only have the absolute error and actual value, let's calculate it using that method.
(1.8/32.7)*100%=~5.5%
Hmmm......
Then, you must be thinking of 19.
Explanation:
Let you numher be x
now
according to question
multiply it by 8 and it becomes 8×x = 8x
Now add 22
so it becomes
8x + 22
now as told in the question take the same number again i.e x for one more time.
multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60
Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,
8x+22 = 6x+60
Do a little azebra
8x -6x = 60 -22
2x = 38
x = 19.
and Tada, your number is here.
