Find the number that should replace the question mark (?): \(?+\frac{3}{5}\) of \(85=100\)
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 49
“Of” means multiply. Find \(\frac{3}{5}\) of 85, then subtract it from 100 to get the missing number.
\(\displaystyle\frac{3}{5}\times85=3\times17=51\)
\(?+51=100\), so \(?=100-51=49\)
