Answer:

xi). We had been given a no. = 5278

⇒ and, according to the question

            If the no.is squared then what will be at the unit place.

so here we needn't to square the whole

⇒we have to just see the unit place of the given no. = 5278

then,

⇒by squaring the unit place of the no. = (8)² = 64

⇒now the unit place of 64 = 4

∴So the answer is option d i.e, 4

xii).  Square root of 0.0144

            =  144 / 10000

      (now by placing square root )

             = √144/ √10000            

            = 12 / 100            

     (as √144 = 12 and √ 10000 = 100)

            = 0.12 is the correct answer.

∴So the correct option is c i.e, 0.12

xiii). The sum of (1+3+5)+(7+9+11)+(13+15+17)+19

               =  9+27+45+19

               = 55 + 45

               = 100    is the correct answer

∴ So the correct option is (c) i.e 100

xiv). 24 is not the perfect square no.

∴ So the correct option is (d) i.e, 24.

xv). After squaring of 400 i.e,

            = (400)²

            = 160000

There are 4 zeroes.

∴ So the correct option is (d) i.e, 4.

hope u will be helped by this.
