20% of a number is more than 20% of 530 by 170. The number is:
1380
Let the number be \(x\).
According to the problem, 20% of \(x\) is more than 20% of 530 by 170. We can write this as an equation:
\(0.20x = 0.20(530) + 170\)
Now, we solve for \(x\):
\(0.20x = 106 + 170\)
\(0.20x = 276\)
\(x = \frac{276}{0.20}\)
\(x = \frac{276}{\frac{1}{5}}\)
\(x = 276 \times 5\)
\(x = 1380\)
Therefore, the number is 1380.
