Solutions:
1. The series is, 11, 11+3, 14+9, 23+27….
2.  The series is 7 + (13 + 1) = 9,
9 + (23 + 1) = 18, 18 + (33 + 1) = 46,
46 + (43 + 1) = 111, 111 + (53 + 1) = 237
3. 5; The series is +17, +34, +51, +68, +85,
ie 7 + 17 = 24, 24 + 34 = 58, 58 + 51 = 109,
109 + 68 = 177, 177 + 85 = 262, …
4.  The series is +(1)2, –(2)2, +(3)2, –(4)2, +(5)2, …
ie 19 + (1)2 = 20, 20 – (2)2 = 16,
16 + (3)2 = 25, 25 – (4)2 = 9, 9 + (5)2  = 34
5. The series is +1.8, +2.2, + 2.6, +3,
+3.4, …
ie 7.4 + 1.8 = 9.2, 9.2 + 2.2 = 11.4, 11.4 +
2.6 = 14, 14 + 3 = 17, 17 + 3.4 = 20.4
6. Let the speed of the boat be 7x and that of the stream be x.
Then, upstream speed = (7x – x) = 6x
And, downstream speed = 7x + x = 8x
Now, upstream speed = 4.2/14×60 = 18 kmph
So, 6x = 18
x = 3 kmph
Thus, speed of stream = 3 kmph
Downstream speed = 8 × 3 = 24 kmph
Time taken downstream to cover 17.6 km
17.6/24×60= 44 minutes
7.  Ratio of profits = 1500 × 12 : 6B : 4C : : 5 : 3 : 3
Capital of B = (1500 x 12)/6 x 3/5 = 1800
Capital of C = (1500 x 12)/4 x 3/5 = 2700
Amount of (B + C) = 2700 + 1500 = Rs 4500
8. Side of square = 567 =  23.81
Length of rectangle = 23.81 + 4 = 27.81
Breadth of rectangle = 23.81 – 4 = 19.81m
Area of rectangle = 27.81 × 19.81
= 550.91 → 551m
9.  Let the cost price of A be Rs x. Then the cost price of B will be 1.2x and the cost price of C will be 1.2x × 1.10 = 1.32x
Then the cost price of D = x × 1.2 × 1.10 + 116 = Rs 1.32x + 116
Now, 1.32x + 116 – x = 500
or, 0.32x = 500 – 116 = 384
x = 384/32 x 100 = 1200
B’s cost price = 1200 × 1.2 = Rs 1440
Hence B paid to A Rs 1440.
10. Ratio of men to women
(15 × 10)M = (25 × 8)W
or, 150M = 200W
or, 3M = 4W
W = ¾ M
1 man’s work = 1/150
(10W + 3M =) 21/2 M can do the work in
1/150 x 21/2 = 7/100 days
65/100 work done by 10 women in (?) days.
8 women – 1 work – 25 days
10 women – 65/100 work in 25 x 8/10 x 65/100 = 13 days
