1).Under the normal speed, 40 minutes for half the distance
Due to rain, time taken will be 40 / (2/3) = 40 × (3/2) = 60 minutes
So, in 20 minutes he has to cover the distance he usually covers in 40 minutes.
So, he has to travel at twice the original speed.
Answer: b)
2).An easy way to solve this question is use x = 3, y=4
7x – 4y = 21 – 16 = 5
3x + y = 9+4 = 13
Required ratio = 5:13
Answer: c)
3).Let the amount be P
Half yearly rate = 5/2 = 2.5%
For the deposit on January, Amount = P (1 + 2.5 / 100)2
For the deposit on July, Amount = P (1 + 2.5 /100)
We can solve the question by substituting options now.
If P = 1600, Amount in January = 1600 × 1.025 × 1.025 = 1681
Amount in July = 1600 × 1.025 = 1640
So total interest = 81 + 40 = 121
Required answer is 1600
Answer: e)
4).Let current year be 2015
In 2005, sum of all ages = 25×45 = 1125
In 2015, sum of all ages = 1125 + (25×10) = 1375
Now 60 year old teacher was replaced by a 54 year old teacher. So we need to subtract 6 from the total.
Sum of all ages in 2015 considering the replacement teacher = 1375 – 6 = 1369
Average = 1369/25 = 54.76
Answer: c)
5).Area of equilateral triangle = 16√3 = √3 (side)2 /4
Or side2 = 16×4 = 64
So each side = 8cm
Perimeter = 8×3 = 24 cm
Since perimeter of the square is 24 cm, each side = 6cm
So area = 6×6 = 36 sq cm
Answer: e)
6).Probability that at least one is defective = 1 – probability that none is defective
 Probability that none is defective = 10C5 / 15C5 = 12/143
Required Probability = 1-12/143 = 131/143
Answer: e)
7).Selling price = Rs. 40
Loss = 20%
Therefore, cost price =  40×100 /(100 - 20) = Rs. 50
Therefore, cost price of each lemon = Rs. 50/45
Now, selling price = Rs. 24
Profit = 20%
Cost price = 24×100/120 = Rs. 20
Number of lemons for Rs. 20 = 20/(50/45) = 900/50 = 18
Answer: d)
8).Let the time taken by Ram, Suresh and Shilpa to finish the work alone be A, B and C respectively
Therefore, 1/A + 1/B + 1/C = 1
Also it is given that,
A = B/3 and C =B/2
3/B + 1/B + 2/B = 6/B = 1, or B = 6
Hence, time taken by Ram, Suresh and Shilpa to finish the work alone is 2 days, 6 days and 3 days respectively
Hence, difference between the number of days taken by Ram and Shilpa, each working alone, to complete the work = 3-2 = 1
Answer: a)
9).Total time = 42 minutes = 0.7 hours.
Average speed = 10 kmph
Total distance = 0.7×10 = 7 km
Let distance walked = W
W/4 + (7-W)/25 = 0.7
Solving W = 2
Answer: a)
10).From 1 to 10 : 1 zero
From 11-100 : 10 zeros (100 has 2 zeros)
From 101 – 900 : 8×20 = 160 zeros
From 901-999 : we have 18 zeros
Total = 1+10+160+18 = 189 zeros
Answer: b)
