Question : If 40% of a number is 290, then what is the number that is 20% more than the initial number?
Option 1: 870
Option 2: 725
Option 3: 825
Option 4: 680
Correct Answer: 870
Solution :
Let the number be $x$.
According to the question,
$\frac{40}{100}\times x = 290$
⇒ $x = 725$
Now, 20% of the number $= 725 × \frac{20}{100} = 145$
So, the required number = 725 + 145 = 870
Hence, the correct answer is 870.
