The word Gotra occurs for the first time in Rigveda. In Hindu society, the term gotra is commonly considered to be equivalent to a clan. It broadly refers to people who are descendants in an unbroken male line from a common male ancestor or patriline.

Generally, the gotra forms an exogamous unit, with the marriage within the same gotra being prohibited by custom, being regarded as incest.

(A+B)'s two days work = 140+150=9200 

Evidently, the work done by A and B duing 22 pairs of days 

 i.e in 44 days = 22×9200=198200 

Remaining work = 1-198200= 1/100

 Now on 45th day A will have the turn to do 1/100 of the work and this work A will do in 40×1100=25

 Therefore,  Total time taken = 4425daya

Circumference = No.of revolutions * Distance covered

Distance to be covered in 1 min. = (66 X1000)/60 m = 1100 m.
Circumference of the wheel = 2 x (22/7) x 0.70 m = 4.4 m.
Number of revolutions per min. =(1100/4.4) = 250.

The pattern followed in the given figures is

One, two, three, one, two, three.....arcs get inverted sequentially. This inversion takes place in an Anti Clock Wise direction.

Hence, figure 1) will come in the next to complete the series.

110% of S.P. = Rs. 616

S.P. = (616 x 100)/110 = Rs. 560

C.P = (110 x 560)/112 = Rs. 500

The given number series is 1 8 36 ? 1100 7701

It follows a pattern that,

1

1 x 3 + 5 = 8

8 x 4 + 4 = 36

36 x 5 + 3 = 183

183 x 6 + 2 = 1100

1100 x 7 + 1 = 7701

Hence, the missing number in the given series is 183.

Let inner radius be r metres. Then, 2πr = 440 ; r = 440×744= 70 m.

Radius of outer circle = (70 + 14) m = 84 m.
