Let 3rd no = 100

Then 25% less than 100 will be ((100-25)/100)*100=75

Similarly 20% less will be 80

Percent is the first number of the second=(75/80)*100=93.75%

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

Long(Standard Procedure)[TYPE1]

Let 3rd no = 100

25% less means in(Percentage) 100 less is (100-25)

1 less is (100-25)/100

Therefore,in 3rd number 100 less is ((100-25)/100)*100 = 75

20% less means in(Percentage) 100 less is (100-20)

1 less is (100-20)/100

Therefore,in 3rd number 100 less is ((100-20)/100)*100 = 80

Percent is the first number of the second =>(75/80)*100=93.75%

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

Long(Standard Procedure)[TYPE2]

Let 3rd no = x

25% less means in(Percentage) 100 less is (100-25)

1 less is (100-25)/100

Therefore,in 3rd number x less is ((100-25)/100)*x = 0.75x

20% less means in(Percentage) 100 less is (100-20)

1 less is (100-20)/100

Therefore,in 3rd number x less is ((100-20)/100)*x = 0.8x

Percent is the first number of the second =>(0.75x/0.8x)*100=93.75%
