Is student multiplied a number by 3 5 instead of 5 3 what is the percentage error in the calculation?
Solution(By Examveda Team) Actual Multiplication = (100 *5)/3 = 500/3. Student multiplied = (100 *3)/5 = 300/5. \%Error = (1600 *100 *3)/(15*500) = 64\%.
What is the error percentage if a number which was supposed to be divided by 5 8 is multiplied by 5 8 instead?
Detailed Solution. Hence, “64 percent” is the correct answer.
What will be the answer if 5 is divided by 5?
1
Answer and Explanation: 5 divided by 5 is equal to 1. In general, anytime we have a number x that is not equal to 0, if we divide x by itself, then the result will be 1.
How do you find percent error 7th grade?
To calculate percentage error, you subtract the actual number from the estimated number to find the error. Then, you divide the error in absolute value by the actual number in absolute value. This gives you the error in a decimal format. From there, you can multiply by 100\% to find the percentage error.
What percentage of numbers from 1 to 70 have 1 or 5 in the units digit?
Such numbers from 1 to 70 are 1, 9, 11, 19, 21, 29, 31, 39, 41, 49, 51, 59, 61, 69. Ans- 1,9,11,19,21,29,31,39,42,49,51,59,61,69=14 no. 20\% numbers from 1 to 70 have 1 or 9 in the unit’s digit. 1,9,11,19,21,29,31,39,41,49,51,59,61,69 this is that series of numbers .
What is the error percentage of 7/5 times 100?
4/5 the of 15 is 12. And 1/3 of 15 is 5 . So error is 12 – 5 = 7. So error percentage = 7/5×100=140\% .
What is the result with error x * (5/3)?
Hence Correct result was x * (5/3)= 5x/3. By mistake he multiplied x by 3/5 . Hence the result with error = 3x/5 Anu fixes the selling price of an article at 25\% above its cost of production.
How to calculate average marks of remaining students of a class?
If we say that 10\% of the students scored 95 marks and 20\% scored 90 marks then calcualte average marks of the remaining students of the class. Lets assume that total number of students in class is 100 and required average be x. => x = 75. 5. If 15\% of 40 is greater than 25\% of a number by 2, the number is
