Find a single equivalent increase if the number is successively increased by 20%, 25% and 30%?

95%

Single equivalent increase of 20%, 25% and 30% =

We know,

20% = \(\frac{1}{5}\)

25% = \(\frac{1}{4}\)

30% = \(\frac{3}{10}\)

According to the question,

      5------------6

      4------------5

      10------------13

---------------------------

     200----------390 ( 190 Increased)

Percentage increase = \(\frac{190}{200}\) × 100 = 95%
