250% of x is increased by 250% means 350% of 250% of x. (250% increase means 350% of original value)
=> 350% of 250% of x = 350
=> \(\frac{350}{100} * \frac{250}{100} * x = 350\)
=>\( x = 100 * \frac{100 }{ 250}\) = 40.
So, Answer will be B
Hope it helps!

Given: 250% of x or 2.5 times x, increased by 250% or 1+2.5 = 3.5 times
Equation:
3.5(2.5(x)) = 350
=> \(x = \frac{(35000)}{35*25}\)
=> x = 40
Option B!
