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.
