b) 8 √3π cubic unit
c) 8√3/5 π cubic unit
d) 8√ 2/3π cubic unit
Answers :
1). Answer: b)
2). Answer: a)
Maximum age of 3 children can be 11, 12 and 13
Sum of their age =11+12+13=36
Average age= 36/3=12
3). Answer: b)
77×335+37×665 – 40×335 = 37×335 + 37×665
= 37 (335+665)
= 37 ×1000
= 37000
4). Answer: c)
a= 1×2×3x…×100 and
b= 101×102×103×104
101 and 103 are prime numbers. And factors of 104 and 108 are in a.
104= 23 x13
108=33x22
Therefore LCM of a and b= 101x103a=10403a
5). Answer: b)
p/q = no. of students in each college
p/q = 2q => p = 2q2
=> 800 < 2q2 < 1200
=> 400 < q2 < 600
Q may be 21, 22, 23, 24.
So the value of q cannot be 25.
6). Answer: c)
Common difference = (20 – 6) = (18 – 4) = (15 – 1) = 14
Required number = (LCM of 20, 18, 15) – common difference = 180 – 14 = 166
7). Answer: c)
Number of leaps taken by Hare = 5
Number of leaps taken by Jackal = 4
4 leaps of Hare = 5 leaps of Jackal
1 leap of Hare = 5/4 leaps of Jackal
- Hare takes 5/4×5 and Jackal takes 4 steps.
Ratio of Speeds= 25/4: 4=25: 16
8). Answer: b)
Let sangeetha’s initial amount = x
Amount Sangeetha gave to Hema = x/4
Remaining amount with Sangeetha = 3x/4
Amount Hema gave to Aparna = x/8
3/4x – 1/8x = 750
x = 1200
Amount received by Hema = x/4 = 1200/4 = 300
9). Answer: d)
Answer: Let the present age of son and father is s and f respectively.
F = 30(s – 20) – 7 —– (i)
F = S + 31 ——- (ii)
S+31 = 30(s – 20) – 7
S = 22
Age of son = 22
10). Answer: d)
Surface area of sphere = 6π
Curved surface area =3πr2= 6π
r =√ 2
So, value of sphere = 4 /3πr3
= 4/3π (√2)3
= 8√ 2/3π cubic unit
