1)a   2)c   3)a   4)c   5)d   6)c   7)e   8)b   9)c   10)a
1).Let the man’s upstream speed be x km/hour and downstream speed will be 2x km/hour
Speed in still water = 1/2 (2x + x) = 3x/2 km/hour
Hence, his downstream speed = 20km/hour
Rate of stream = 1/2 (20-10) = 5km/hour
Answer: a)
2).Let the incomes of two persons be 5x and 4x
let the expenditures of them be 9y and 7y
Each person saves Rs. 500
Therefore,
5x – 9y = 500
4x – 7y = 500
Solving the above equations,
20x – 36y = 2000
20x – 35y = 2500
Therefore,
5x = 500 + 9y
5x = 500 + 9(500) = 5000
Hence, their salaries are Rs. 5000 and Rs. 4000
Answer: c)
3).Let the sum be S, time be ‘n’ years for 6%. n+2 years for 5%
2400 = S + S ×n × 6/100
2400 = S + S × (n+2) × 5/100
So, 6n = 5(n+2) or n = 10 years.
2400 = S + S × 10 × 6/100 = 1.6S
S = 2400/1.6 = 1500
Answer: a)
4).Total expenditure for first 3 months = 2200 × 3 = Rs 6600
Total expenditure for next 4 months = 2250 × 4 = Rs9000
Total expenditure for last 5 months = 3120 × 5 = Rs 15600
Total expenditure = 6600 + 9000 + 15600 =Rs 31200
Total income = expenditure + savings = 31200 + 1260 = Rs 324060
Average monthly income = 32460/12 = Rs 2705
Answer: c)
5).The longest pencil that can be fit will be the diagonal length
Required length = (122 + 102 +82)1/2 ≈17.5cm
Answer: d)
6).The various possible cases are:
i. 2 women and 3 men = 5C2 × 8C3 = 10 × 56 = 560
ii. 3 women and 2 men = 5C3 × 8C2 = 10 × 28 = 280
iii. 4 women and 1 men = 5C4 × 8C1 = 5 × 8 = 40
Total = 560 + 280 + 40 = 880
Answer: c)
7).Let say he purchases 3 litres of milk whose cost is Rs. 7.20
He adds 1 litre of water and the mixture of 4 litres is sold at Rs 2.88 × 4 = Rs11.52
Profit percentage = (11.52 – 7.20) × 100.0/7.20 = 4.32 × 100.0/7.2 = 60%
Answer: e)
8).Amount of work done by A in one day = 1/8th of the total work
B can break 1/3rd of the work in one day
Therefore, if both of them are working together then the work done in one day = 1/8 – 1/3 = -5/24
Negative sign indicates that, work is more broken than built in one day
Amount of work done by A in four days = 1/2 of the  total work
Work done by both A and B for two days = -10/24 = -5/12
Total work done by the end of 6 days = 1/2 - 5/12 = 1/12
Remaining work = 1 – 1/12 = 11/12
Time taken by A to finish 11/12th of the work = 11/12 × 8 = 22/3 days
Answer: b)
9).Let the numbers be a,b
A = 27m, b = 27n where m, n are co-prime
27(m + n) = 216, or m+n = 8
M = 1, n = 7 and m = 3, n = 5 are the only 2 co – prime pairs possible.
So we have 2 pairs: (27 , 189) and ( 81, 135)
Answer: c)
10).Ajay reads at average rate of 30 pages per hour ie. 1 page in every two minutes.
Therefore, by 5:20 PM, he would have covered 25 pages
By 6:20 PM, Ajay would have read 25+30 pages and Vikram would have read 40 pages.
By 7:20 PM, Ajay would have read 85 pages and Vikram would have read 80 pages
In next half an hour, Ajay would cover 15 pages and he will finish 100 pages
Vikram would cover 20 pages and he will also finish 100 pages
Hence, both of them will be on same page at 7:50
Answer: a)
