Find the number that should replace the question mark (?): 35% of 260 + \(13\times6=13\times\,?\)
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 13
Work out the left side completely, then divide by the number that multiplies the question mark.
35% of 260 \(\displaystyle=\frac{35}{100}\times260=91\)
\(13\times6=78\)
Left side \(=91+78=169\)
\(13\times\,?=169\), so \(?=169\div13=13\)
