   D) Rs. 465, Rs. 575
   
   Answer

   B) Rs. 575, Rs. 465
   Explanation:
   total profit is 1040, out of which A gets 25% separately, so 25/100 * 1040 = 260
   so now 1040 – 260 = 780 should be distributed among both in ratio 2100 : 3100 or 21 : 31
   A gets 260 + (21/52)*780 and B gets (31/52)*780
   
   
7. 12 men alone can complete a piece of work in six days, whereas 10 men and 21 women take three days to complete the same piece of work. In how many days can 12 women alone complete the same piece of work?
   A) 10
   B) 9
   C) 11
   D) 8
   
   Answer

   B) 9
   Explanation:
   12 M = 6 D
   so, 1 M = 12*6 = 72 D, this gives 1 M does the work in 72 days
   now, 10 M + 21 W = 3 D
   Let 1 W does the work in x days
   or 10* (1/72) + 21 (1/x) = 1/3
   21 (1/x) = 7/36
   x = 108
   1 W does work in 108 days, so 12 women in 108/12 = 9
   
   
8. The ratio between the three angles of a quadrilateral is 1 : 4 : 5. The value of the fourth angle of the quadrilateral is 60°. What is the difference between the value of the largest and the smallest angle of the quadrilateral?
