A boy did 32 sums in a test. He got 75% correct. How many did he get wrong?
If the boy got 75% correct on the test, it means he got 25% wrong. To find how many sums he got wrong, we can first find what 25% of 32 is:
25/100 x 32 = 8
Therefore, the boy got 8 sums wrong in the test.
To find out how many sums the boy got wrong, we first need to calculate how many sums he got correct.
To do this, we multiply the total number of sums (32) by the percentage he got correct (75% or 0.75).
Number of sums correct = 32 * 0.75 = 24.
Now, to find the number of sums he got wrong, we subtract the number of sums he got correct from the total number of sums.
Number of sums wrong = Total number of sums - Number of sums correct = 32 - 24 = 8.
Therefore, the boy got 8 sums wrong.
To find out how many sums the boy got wrong, we first need to calculate the number of sums he got correct:
Correct = Total sums * Percentage correct
Correct = 32 * 75/100
Correct = 24
Now, we can find the number of sums the boy got wrong:
Wrong = Total sums - Correct
Wrong = 32 - 24
Wrong = 8
Therefore, the boy got 8 sums wrong.
