Answers:
- Answer: (A)
The prime numbers between 1 and 20 are 2, 3, 5, 7, 11, 13, 17 and 19.
Average = Sum of all numbers /counting of numbers
Average = (2+ 3 +5+ 7+ 11+ 13+ 17+ 19)/ 8 = 9.625.
- Answer: (D)
Average = Sum of all numbers /counting of numbers
15 =( 4+ 17+ 5 +8 +12+ 13+ 7+ 19+ 24+ 21+ a+ 14)/ 12
144 + a = 180
a = 36.
- Answer: (A)
C.I. for 1st year = 5% of 7200 = Rs. 360
C.I. for 2nd year = 5% of 7200 + 5% of 360 = 360 + 18 = Rs. 378
C.I. for 2 years = 360 + 378 = Rs. 738
- Answer: (A)
Population in 2006 = 15,80,000
Rate of growth = 10%
Population in 2008 = 1580000(1+ 10/ 100)2 = 1580000 × 1.1 × 1.1 = 19,11,800
- Answer: (D)
Total distance covered by Sachin = (100 × 2) km + (120 × 3) km = 560 km
Total time taken = 5 h
∴ His average speed = 560/ 5 kmph = 112 kmph
- Answer: (C)
Let HCF be ‘a’ and LCM be ‘a + 15’.
Product of LCM and HCF = 54 a(a + 15) = 54
a2 + 15a = 54
a2 + 15a – 54 = 0
(a – 3)(a + 18) = 0
a = 3, -18.
HCF cannot be negative.
Therefore, HCF = 3 LCM = a + 15 = 18
- Answer: (D)
Let the container contain 8x and 3x kg of mixture of pulse A and B, respectively.
Quantity of mixture drawn off = 8 kg
Quantity of pulse A drawn off in mixture = 8x- 8 / 11 x 8 = (88x – 64 )/11
Quantity of pulse B drawn off in mixture = 3x – 8/ 11 x 8 = 33x -24/ 11
As the new ratio of the mixture is 8: 5.
( 88x-64)/ (33x -24)=18/ 7
x = 2
Therefore, initial quantity of pulse A = 8 × 2 = 16 kg.
- Answer: (B)
Let the three consecutive odd integers be x – 1, x, x + 1.
According to the question, x + x + 1 = 8 + (x – (x – 1))
2x + 1 = 8 + 1
2x = 8
x = 4
x – 1 = 4 – 1 = 3
x + 1 = 4 + 1 = 5
Clearly, the smallest of the three odd integers is 3.
- Answer: (B)
Let L and B be the original length and breadth of the rectangle, respectively
Original area of rectangle = LB
New area of rectangle = 1.5L × 0.7B = 1.05LB = 105% of LB
Percentage increase in area of rectangle = 5%
- Answer: (A)
Let time taken by leakage to empty the tank = X minutes
1 /45 – 1/x= 1/(45+ 15)
1 /X = 1/45 – 1/ 60 = 1/ 180
X = 180
Time taken by leakage to empty the tank = 180 minutes = 3 hours
