- 6
Answers:
1). Answer: a
a/b+b/a=1
=> (a2+b2)/ab=1
=> a2+b2=ab
=> a2+b2-ab=0
Therefore a3+b3=(a+b)(a2-ab+b2)=0
2). Answer: C
ABCD is acyclic parallelogram.
∠A+∠C=180
2∠C=180
∠C=90
3). Answer: B
sinѲ+ cosecѲ= 2
sinѲ+1/ sinѲ=2
sin2 Ѳ-2 sinѲ+1=0
(sinѲ-1)2=0
sinѲ=1=> cosecѲ=1
sin100Ѳ+ cosec100Ѳ=1+1=2
4). Answer: D
Time taken to cover 40 km at the speed of 5 km/hr =40/8=5 hrs
Fixed time= 5 hrs – 40 minutes= 4 hrs 20 minutes
Time taken to cover 40 km at the speed of 10 km/hr= 40/10=4 hrs
Required time= 4 hrs 20 minutes-4 hrs = 20 minutes earlier
5). Answer: c
2x+8=23( 2x+1)
X+8=3(2x+1)
X+8=6x+3
5x=5
X=1
6). Answer: a
2/5 = 0.40 and 4/9 =0.44
3/7=0.42
1/2=0.5
2/3=0.66
4/5=0.8
7). Answer: b
17200 = (18=1)200
17200/18 = (18=1)200/18
Remainder=1
8). Answer: a
8x*2: 5x*12: 7x*12= 4:15:21
80000/40x*(21-15)x=12000
9). Answer: b
(5-x)=6/x
5x-x2-6=0
x= 2,3
Least number is 2
10). Answer:d
cos4A− sin4A = (cos2A+sin 2 A) (cos 2A-sin 2A)
=1(cos2A-(1-cos2A)) ∴ (cos2x+sin 2x =1)
=2cos2A-1
11). Answer: c
The possible values of X are 10,20,30,60 and 90
