Answers:
1). Answer: B
First Number ×Second number = LCM ×HCF
28× x= 14×140
X = (14×140)/28 = 70
2). Answer: C
(22)10 × (73)× (24)2 ×11× (2×5)2
= 220×73×28×11×22×52
= 230×73×111×52
Total number of Prime factors
= 30+2+3+1 =36
3). Answer: A
20×30 = 600
20×30 =600
1200/40 =30
4). Answer: B
Let the value of X =3 y =4
4x + 5y: 5x – 2y = 4(3) + 5(4) : 5(3) – 2(4)
12 + 20 : 15 – 8
32: 7
5). Answer: A
Let salary = 100
After 20 % increased the salary = 120
Rs. 120 is decreased by 20 % then the salary is 120 – 24 = 96
100 – 96 = 4 % Decreased
6). Answer: C
P = 5 S.I = 3 N = 10 R =?
S.I = PNR /100
3 = (5×10×R)/100
R = 300/50 = 6%
7). Answer: D
tan (5x – 10°) = cot (5y + 20°)
tan (5x – 10°) = tan (90° – (5y + 20°) )
5x – 10° = 70° – 5y
5(x+y) = 80°
x+y = 16°
8). Answer: b
If Amit sells the laptop with the profit = (50,000×120)/ 100 = 60,000
SP at 10 % loss = (50,000×90)/ 100 = 45,000
Difference of the amounts = 60,000 – 45,000 = 15,000
9). Answer: C
Speed of boat = (U+V)/2 = (8+6)/2 = 14/ 2 = 7kmph
10). Answer: A
115% of 300 + 190% of x = 60% of 400
145 + 190% of x = 240
19x/10 = 95
X= 950/19
X= 50
