(A) 4
(B) 5
(C) 6
(D) 7

The answer is: (B) 5
SOLUTION
(0+2+5+6+7+10)/6 = 30/6 = 5

(A) 10
(B) 90
(C) 100
(D) 180

The answer is: (C) 100
It is obvious to note that 90% of 100 is 90.

(A) 110
(B) 120
(C) 130
(D) 140

The answer is: (D) 140
SOLUTION
Let x be the number whose 20% is 40. Then,

(A) 12
(B) 24
(C) 16
(D) None of these

The answer is: (B) 24
40% of 60 = (40/100)×60=24

Choose the answer which best completes the number pattern:
16, 24, _____, 40, 48
(A) 30
(B) 32
(C) 34
(D) 36

The answer is: (B) 32
8×2=16, 8×3=24, 8×4=32, 8×5=40

(A) 18
(B) 27
(C) 48
(D) 84

The answer is: (D) 84
Combinations = [9!]/[3!(9-3)!] = [9.8.7.6!]/[3!.6!] = 504/6 = 84

(A) three time
(B) six times
(C) nine times
(D) none of these

The answer is: (C) nine times
Area = πr²
If radius is increased by 3 times, then
NewArea = π(3r)² = π9r² =9(πr²) =9(Area)
So, area is increased by 9 times.

(A) 1 : 20
(B) 1 : 25
(C) 1 : 40
(D) 1 : 80

The answer is: (A) 1 : 20
Solution
The ratio of 20cm and 4m is: 20cm/4m = 20cm/400cm (1 meter = 100 centimeters)
Hence, ratio = 20/400 = 1/20 = 1:20

(A) 1:20
(B) 1:25
(C) 1:40
(D) 1:80

The answer is: (D) 1:80
Solution
The ratio of 50m and 4km is: 50m/4km = 50m/4000m (1 kilometer = 1000 meters)
Hence, ratio = 50/4000 = 1/80 = 1:80
