Solutions (1-5):

1.       (3)              
2.       (2)              
3.       (2)              
4.       (5)
5.       (3) Ratio =24/16= 3 : 2

Solutions (6-10)

6. 3;      Both statements are required for answer.
              SP = 12000, Profit = 20%
              Cost Price = 1000 ie profit = 2000
              Total profit = 2000 × 20 = 40000
7. 3;      From statement I:
              x = 4y                             ...(i)
              From statement II:
              x – 5 = 7(y – 5)
              7y – x = 30                    ...(ii)
              Solving equations (i) and (ii), x = 40, y = 10
8. 5;      Data is not sufficient to find the answer.
9. 4;      Both statements alone are sufficient to answer.
              Let be speed = v, distance = x, time = t
              t =  x/v           ...(i)
              From statement I:
              x/5v/4=t – 20
              4x/5v= t – 20
              x/v = 5/4(t – 20)           ...(ii)
              From (i) and (ii), t =  5 / 4(t – 20)
              4t = 5t – 100
              t = 100 seconds
              From statement II:
              x / v / 2 = t + 100
              2x / v = t + 100
              t + 100 = 2t
              t = 100 seconds
10. 3;    Both statements are required to answer the question.
              From statement I:
              1/v =  10 seconds                   (1 = length, v = speed)
              From statement II:
              v = 10 m/sec
              1 = 10 × v = 100 m
