1). a) 2). d) 3). d) 4). b) 5). c) 6). e) 7). c) 8). b) 9). e) 10). d)
Solution:
1).No. arrangements = 2! ร (5! / 2!) = 120

2).Sum = (n / 2) [2a + (n โ 1)d]
Or, 190 = (n / 2) [2 + (n โ 1)4]
Or, 190 = n(2n โ 1) โด n = 10

3).16 men do the whole (100 %) work in 10 ร 2 = 20 days
10 women do the whole (100 %) work in (15 ร 100) / 75 = 20 days
16 men + 10 women do the whole work in
(20 ร 20) / (20 + 20) = 10 days
โด 8 men + 5 women do the whole work in 20 days
โด required days = 20(80 / 100) = 16 days

4).Total employees of A = 500 ร (100 / 25) = 2000
Total employees of B = 252 ร [100 / (100 โ 16)] = 300
โด Total strength of A and B = 2300

5).Let the side of the square be x.
โด circumference of base of cylinder = x
โด radius = x ร (7 / 44) = 7x / 44
Ratio = 7x / 44x = 7 : 44

6).Distance = [(60 ร 60) / (60 โ 20)] ร (50 / 60) = 25 km

7).Required ratio = (45 ร 36) / (55 ร 68) = 81 : 187

8).R + S = S + M + 15
R โ M = 15                             โฆ(i)
And, (R + S + M) / 3 = (R + S) / 2
Or, 3R + 3S = 2R + 2S + 2M
โด M = (R + S) / 2                    โฆ(ii)
Putting (ii) in (i),
R โ [(R + S) / 2] = 15
R โ S = 30

9).6x โ 9 = 16x โ 23
Or, 10x = 14
โด x = 7 / 5
Now, โต (1 / N) โ x2= 6x โ 9
Or, (1 / N) โ (49 / 25) = (42 / 5) โ 9 = -3 / 5
Or, (1 / N) = (49 / 25)  – (3 / 5 )
= (49 โ 15) / 25 = 34 / 25
โดN = 25 / 34
