If I 1 = ∫ 0 1 1 - x 50 100 d x and I 2 = ∫ 0 1 1 - x 50 101 d x such that I 2 = α I 1 then…

If I1=011-x50100dx and I2=011-x50101dx such that I2=αI1 then α equals to :
  1. 50495050
  2. 50505049
  3. 50505051
  4. 50515050

Solution

Given 

α=I2I1=011-x50101dx011-x50100dx
Now,

I2=011-x501-x50100dx
I2=I1-01x.x491-x50100dx
I2=I1--x1-x50101505001-011-x501015050dx
I2=I1-I25050
α=I2I1=50505051
