Sum of cubes of first n natural numbers = (n(n+1)/2) 2

Question 1

30% of 30% of ? = 90

a. 1000
b. 10
c. 10000
d. 100
e. 100000

Answer : a. 1000

Let the number we should find be N
Then, 30% of 30% of ? = 90
Or (30/100) x (30/100) x N = 90
Or (900/10000) x N = 90
Or N = (90 x 10000) / 900 = 1000


Question 2

?% of 50% of 200 = 20

a.200
b.20
c.400
d.40
e.800

Answer : b. 20

Let the unknown number be L

Then, ?% of 50% of 200 = 20
Or L/100 x 50/100 x 200 = 20
Or L = (20 x 100 x 100) / (50 x 200) = 20


Question 3

25% of 125% of 100 = ?

a. 3125
b. 31.25
c. 3.125
d. .3125
e. 31250

Answer : b. 31.25

Let the number to be found be M
Then, 25% of 125% of 100 = M
Or (25/100) x (125/100) x 100 = M
Or 31.25 = M


Question 4

10% of ?% of 1000 = 150

a. 150
b. 1500
c. 300
d. 3000
e. 30

Answer : a. 150

Let the number to be found be N
Then, 10% of N% of 1000 = 150
Or (10/100)x(N/100)x1000 = 150
Or N = (150 x 100 x 100)/(10 x 1000) = 150
