Answer 1

Hey there !

Solution:

10 ( i ) 25 is increased to 45. To Calculate the percentage change

Change in Value = Final Value - Initial Value

=> Change in Value = 45 - 25 = 2

$Percentage \: Change = \dfrac{ \text{ Change in Value} }{Final \: Value} \times 100 \\ \\ \implies Percentage \: \: Change = \dfrac{ 20}{ 45} \times 100 \\ \\ \implies Percentage \: \: Change = \dfrac{2000}{45} = 44.45 \: \%$

Hence the Percentage Change is 44.45 %
