   Given expression = √15625 + √15625/100 + √15625/10000

   Correct Option: C

   Given expression = √15625 + √15625/100 + √15625/10000
   = (125 + 125/10 + 125/100)
   = (125 + 12.5 + 1.25)
   = 138.75

   Let , √1296 / N = N / 2.25
   Then, 36/N = N /2.25 or N²= 36 x 225/100

   Correct Option: D

   Let , √1296 / N = N / 2.25
   Then, 36/N = N /2.25 or N²= 36 x 225/100
   ∴ N = √(36 x 225) /100 = (6 x 15) / 10 = 9

   Given expression = √0.0009 / √0.01
   = √0.0009 / 0.0100
   = √9 / 100
   = √9 / √100

   Correct Option: B

   Given expression = √0.0009 / √0.01
   = √0.0009 / 0.0100
   = √9 / 100
   = √9 / √100
   = 3 / 10
   = 0.3

   √0.121 = √0.1210
   = √1210/10000
   = √1210 / 100
   = 34.7 / 100

   Correct Option: C

   √0.121 = √0.1210
   = √1210/10000
   = √1210 / 100
   = 34.7 / 100
   = 0.347.
