6. A train of length 320 meters crosses two consecutive poles completely in 49 seconds with a speed of 20 m/s. What is the distance between two consecutive poles?
   555
   600
   650
   660
   666
   Option D
   Let the distance between the two consecutive poles be x m.
   320+x = 49*20
   => 320+x = 980
   => x = 660 m

    

7. A man sold 2 books at the same price, one at a profit of 20% and other at a loss of 10%. If the total selling price of both books is Rs. 1800,then find the total cost price of both the books.
   1550
   1700
   1570
   1750
   1520
   Option D
   SP of each book = 1800/2 = 900
   Total CP of both books = 900/1.2 + 900/0.9
   = 750+1000 = Rs.1750

    

8. If the sum of all the interior angles of a regular polygon is 2520 degree. Then find the number of sides of the regular polygon.
   10
   20
   16
   14
   18
   Option C
   Sum of all the interior angles of a regular polygon
   = (n-2)/2*360
   => 2520 =(n-2)/2*360
   => n = 16

    

9. Govind lent Rs.12000 to Vivek for 3 years and Rs. 4000 to Ramu for 4 years at the same rate and received Rs. 4160 as simple interest altogether from both. Find the rate of interest.
   7%
   4%
   6%
   8%
   5%
   Option D
   Let the rate of interest be r% p.a.
   (12000*3*r)/100+(4000*4*r)/100 = 4160
   => 360r + 160r = 4160
   => 520r = 4160
   => r = 8%

    

10. The average age of all workers in a factory is 40 years. The average age of male workers is 50 years and that of female workers is 30 years. If the number of female workers is 12, then the number of male workers .
    18
    12
    10
    14
    19
    Option B
    Let the number of male workers be x .
    x*50 + 12*30 = (x+12)*40
    => 50x + 360 = 40x + 480
    => x = 12
