Beginning of the year -> x
End of first quarter -> x+ 20/100*x = 1.2x
End of second quarter-> x(since it says it increased 50% from what was in the beginning of the year) + 50/100*x
=x + 50/100*x
= 1.5x
Percent Increase/Decrease(between end of first quarter to end of second qaurter)
= New - Original / Original * 100
= (1.5x - 1.2x ) / 1.2x * 100
= .3x/1.2x *100
= .3/1.2 * 100
= 3/12*100
= 25%
Hope this helps!
