Q. 1
The number of prime numbers between 1 to 20 is ..........
[1] 6
[2] 8
[3] 9
[4] 7
Wrong! You Entered : 0, Correct Answer : 2.
Prime numbers between 1 to 20
2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 = total 8 numbers.
2 : 2. To Form the Greatest and the Smallest Numbers
Q. 2
Find the difference between the greatest and the smallest three digit
numbers formed by using 5, 0 and 1 each only once.
[1] 400
[2] 405
[3] 495
[4] 404
Wrong! You Entered : 0, Correct Answer : 2.
Greatest number using 5 , 1 , 0 = 510 (Descending)
Smallest number using 5 , 1 , 0 = 105
(0 can not come at hundred's place , because that will make that number
2 digits number)
Difference 510 – 105 = 405
3 : 3. Place Values
Q. 3
Find the difference in the place values of 5 in the number 9.5015.
[1] 5000
[2] 4995
[3] 0.04995
[4] 0.4995
Wrong! You Entered : 0, Correct Answer : 4.
Place value of 5 on the left side = 0.5
Place value of 5 on the right side = 0.0005
Difference = 0.5 – 0.0005 = 0.4995

Q. 8
In the following figure find the distance between points A and B?
[1] 5 units
[3] -3.75 units
Wrong! You Entered : 0, Correct Answer : 1.
[2] 3.75 units
[4] can not be determined
<www.mahaedutechnet.org> There are 2 parts between point C and the point associated with
number 2.25
Distance between these two points = 4.75 – 2.25 = 2.5
2 parts = 2.5
1 part = 1.25
There are 4 parts between point A and B.
Distance between A and B = 1.25 × 4 = 5 units.

16 : 16. Percentage
Q. 16 During the last year there were 500 students in a school. Amongst
them 320 were boys and 180 were girls. This year, the total number
of students is the same, but there are 280 boys and 220 girls. Find
the percent increase and percent decrease in the number of boys and
girls with respect to the total number of students. (2004)
[1] Boy 8% decrease and girls
[2] Boy 10% decrease and girls

8% increase
Wrong! You Entered : 0, Correct Answer : 4.
In 500 students, 40 boys were reduced
500 : 40
100 : b
b = (40 x 100) / 500 = 8% reduction in boys w.r.t. total no of students.
In 500 students, 40 girls were added
500 : 40
100 : g
g = (100 x 40)/500 = 8% addition in girls w.r.t. total no of students.

the rate of 12 pcpa, find the amount of loan taken by Ravi.
[1] Rs. 4920
[2] Rs. 5000
[3] Rs. 4800
[4] Rs. 5120
Wrong! You Entered : 0, Correct Answer : 2.
Let us assume that simple interest = x
Principal = 6200 – x
R = 12
N = 2
<www.mahaedutechnet.org> Interest = Rs. 1200
Principal 6200 – 1200
= Rs. 5000
18 : 18. Discount, Commission and Rebate
Q. 19 On account of Diwali festival, a cloth merchant declared 18% rebate
on the cloth. Ujwala purchased two sarees of Rs. 450 and Rs. 770
and some clothes worth Rs. 620 from his cloth-mart. How much
money did Ujwala pay? (2000)

20 : 20. Time, Work and Speed
Q. 21 40 workers can dig 30 pits in 60 days. How many days will be
required by 20 workers to dig 15 pits? (1992, 2004)
[1] 30
[2] 60
[3] 90
[4] 50
Wrong! You Entered : 0, Correct Answer : 2.
Total work = 40 × 60 worker – days = 30 pits.
to dig 1 pit =
worker – days.
to dig 15 pits = 15 × 80 worker – days.
if 20 workers are there , they will take
days.

ago, the ratio of their ages was 7:3. Find mother's present age.
(1996)
[1] 45
[2] 49
[3] 50
[4] 50
Wrong! You Entered : 0, Correct Answer : 1.
Assume mother's present age is x
Before 10 years mother's age was x – 10
Daughter's present age = 70 – x
Before 10 years daughter's age = 70 – x – 10
= 60 – x
<www.mahaedutechnet.org> 3 (x – 10) = 7 (60 – x)
3x – 30 = 420 – 7x
7x + 3x = 420 + 30
10x = 450
x = 45
Mother's present age = 45 years.

Q. 30 The measures of the angles of a triangle are (5x+10)0, (3x+15)0 and
(x+20)0 respectively. What type of triangle is it? (2004)
[1] Right-angled
[2] Obtuse-angled
[3] Acute-angled
[4] Scalene triangle
<www.mahaedutechnet.org> Wrong! You Entered : 0, Correct Answer : 3.
(5x + 10) + (3x + 15) + (x + 20) = 180 (angles of a triangle)
9x + 45 = 180
9x = 180 – 45 = 135
x = 15
5x + 10 = 15 × 5 + 10 =
, 3x + 15 = 3 × 15 + 15 =
x + 20 = 15 + 20 = 35
So the given triangle is an acute triangle.
