Solutions:
1. D) Required difference = Take average after calculating total difference
= (28 + 8 + 104 + 6 + 22)/5 = 168/5 = 33.6
2. A) In MP, the difference in 2015 and 2016 is 6
3. C) Required % = 128/1800 × 100 = 7%
4. E) Required % = (12 + 32)/30 × 100 ≈ 147%
5. A) Required ratio = 60 : 218 = 30 : 109
6. E) Let two digit number be 10x + y.
From I, either x – y = 27/9 = 3
Or, y – x = 27/9 = 3
From II, x – y = 3 or y – x = 3
From III, x – y = 3
Hence, Even by (I) + (II) + (III) we cannot obtain the number.
7. B) From I and II, 10 women can finish the work in 1 day
= 7/24 – 1/6 = (7 – 4)/24 = 1/8
10 women can finish the work in 8 days.
From II and III,
Let 10 men can finish the work in x days and 10 women can finish the same work in y days.
Hence,
1/x + 1/y = 7/24 ...(i)
and from III – II,
3/x + 4/y = 1 ...(ii)
from (i) & (ii)
y = 8 days
Again from I and III
3/6 + 4/y = 1
y = 8 days
8. E) From I, If P = 100
A = 200 and SI = 200 – 100 = 100
Rate = SI × 100/(P × T)
= 100 × 100/(100 × 5)
= 20%
From II and III, Rate
= 400 × 100/2000 × 1
= 20%
Hence, either I alone or II + III will be sufficient.
9. A) From I, Let present age of Rakesh be x yr and age of his father be 2x yr.
From I and II,
(x + 5)/(2x + 5) = 6/11
12x + 30 = 11x + 55.
x = 25 yr
From I and II, age of Rakesh = 25 yrs.
Hence, only from I & II, age of Rakesh and his father can be obtained.
10. E) From I and II.
Length = 3x = 48 m
x = 16
Breadth = 2x = 32 m
Hence, Area of floor = 48 × 32
Cost of flooring = 48 × 32 × 850 = Rs. 1305600
From I and III, 2(l + b) = 160
2(3x + 2x) = 160
10x = 160
x = 16
Length = 3 × 16 = 48 m
Breadth = 2 × 16 = 32 m
Cost of flooring = (48 × 32) × 850 = 1305600
Similarly, from II and III, we can find I = 48 m and b = 32 m and Total cost of flooring = 1305600
