When 35 is subtracted from a number, it becomes 80% of the number. What is four-fifths of that number?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 140
If what is left is 80% of the number, then the 35 taken away is the other 20% of it.
20% of the number \(=35\)
Number \(=35\times5=175\)
Four-fifths of the number \(\displaystyle =\frac{4}{5}\times175=140\)
Four-fifths of the number is 140.
