(a) 97
(b) 103
(c) 99
(d) 101
Sol.

Q3. If x^2+1/x^2 =34, then find the value of x+1/x 
(a) 4
(b) 6
(c) 8
(d) 17  
Sol.
x^2+1/x^2 =34 
⇒ (x+1/x)^2-2×1/x=34  
[a^2+b^2=(a+b)^2=2ab] 
⇒ (x+1/x)^2=36 
⇒ x+1/x=6 

Q4. The ratio of the length to the breadth of a rectangle is 2 : 1. Its perimeter is 60 cm, find its area.  
(a) 250 sq cm 
(b) 200 sq cm
(c) 300 sq cm 
(d) 205 sq cm 
Sol. 
2(2x + x) = 60 cm 
⇒ x = 10 cm 
∴ Area = 2x 
x = 2(100) = 200 cm2 

Q5. What value should come in place of question mark (?) 
 (1.06+0.04)^2- ? 4×1.06×0.04   
(a) 1.0404 
(b) 1.4
(c) 1.5
(d) 1.45
Sol. 
(1.06+0.04)^2- ?=4×1.06×0.04 
⇒ 1.06^2+0.04^2+2×1.06×0.04 – ? 
= 4 × 1.06 × 0.06 
⇒ ? =1.06^2+0.04^2-2×1.06×0.04 
=(1.06-0.04)^2=(1.02)^2 
i.e.  = 1.0404 

Q6. Sum of first 20 terms of the Arithmetic Progression (A P) 11, 7, 3,….is 
(a) 20
(b) –540
(c) 980
(d) –65 
Sol.
 n = 20 
First term a = 11 
Sum =n/2 (2a+n-1d)=20/2 [2(11)+19(-4)] 
= 10(22 – 76) = – 540  

Q7. On decreasing the radius of a sphere by 20%. By what per cent its volume will be decreased?  
(a) 20
(b) 28.8
(c) 57.6
(d) 48.8
Sol.
Let original radius = 100 units 
Then, new radius = 80 units 
Per cent decrease in volume 
=(4/3 π(80)^(3 )- 4/3 π(100)^3)/(4/3 π(100)^3 )×100 
=(10^3 (8^3-10^3 ))/(10^3.10^3 )×100 
=((512-1000)/1000) ×100=-48.8  

Q8.  If a card is drawn from a pack of cards, what is the probability of getting a black coloured card? 
(a) 1/3
(b) 1/2
(c) 3/4
(d) 3/8

Required probability = 1 – probability 
(drawing a green ball) 
=1-4/24=5/6 
Q10. A number when tripled and decreased by 15 we get the result as 120. Find the number.
