Answers :
1). Answer: d)
Assume that 3 kg of pulse of type A, 1 kg of B and 6 kg of C are used in the hotel
Total Cost= 3×80+1×54+6×72 = 726
Average cost= 726(3+1+6) = 72.6
2). Answer: b)
3). Answer: c)
Substitute a = 1, b = 1 and c = 1
Answer = ¼
4). Answer: a)
Relative Speed = 55 −19 = 36 km/h = 36 × 5/18 = 10 m/s
First bus replaces the bus in 12 seconds
Distance covered = 12×10 = 120 m
12 —- 120
5 —— ?
? = 50 m
5). Answer: d)
MN = 805
M = 805/N —– (i)
N – 3 = 5/8 (M – 3)
8N – 5M = 9 —– (ii)
Substitute (i) in (ii)
8N – 5(805/N) = 9
8N2 – 4025 = 9N
N = 23
6). Answer: d)
Diameter of circle = 56
Radius of circle, r = 28
22/7×28×28 = 2464
Area of Square = 324
a2 = 324
Side of a Square, a = 18
Perimeter of Square: Circumference of Circle = 4a: 2πr
=72: (2×22/7×28)
=72: 176
= 9: 22
7). Answer: a)
48(s1-s2)=36(s1+s2)
48s1-48s2=36s1+36s2
12s1=84s2
S1:s2=84:12=7:1
8). Answer: c)
Let the side of a square =x
Perimeter of Square= 4x
Speed = Distance/ Time
=4x/(x/150+x/200+x/300+x/600)
=4x/(10x/600)
=240 kmph
9). Answer: c)
Let Label price be Rs. 100.
It is sold at 30% loss i.e Rs. 70
1/3 of Label Price = 70
Label Price = 70× 3= 210
Profit %= 110/100 ×100
= 110% profit
10). Answer: c)
Given x2 – x – 1
=>x2 – 1 = x
x2 – 1 – 1 = x – 1
x2 – 2 = x – 1 …..(i)
Again, x2 – x – 1 = 0
x2 – x = 1 ….(ii)
Value of x3 – 2x + 1
= x(x2 – 2) + 1
= x(x – 1) + 1 [from i]
= x2 – x + 1
= 1 + 1 [from ii]
= 2
