1.      = 0.466,    = 0.652,    = 0.724 . Therefore 21:29 is greatest.
15          23          29
Another method. Out of 7:15(= 21: 45) and 21:29 , 21:29 is greatest. out of 15:23 and 21:29,
the lcm between 15 and 21 is 105. Between 105:161 and 105: 145, 105:145 is greatest.

8.Let the speed of the train be x km/hr and that of the car be y km/hr.

Then,       +      = 8 or + = . And                +     =       or + =         .

Solving (i) and (ii) we get x = 60 and y = 80. ∴ Ratio of speeds = 60: 80 = 3:4.
9.Clearly, the two will meet when they are 726 m apart. To be (4.5 + 3.75 =) 8.25 km apart,
100 726                 242

10.     At the time of meeting, let the distance travelled by the second train be x km. Then,

distance covered by the first train is (x + 100) km. ∴        =

50x = 40x + 4000       x = 400.

1. D. I + I leads to no conclusions, both this conclusions are invalid.
2. D. A + E = E. Thus the conclusion should be ‘No beautiful girls are smart’.
3. D. I + I = no conclusion. Thus both are invalid.
4. A. I + E = O which leads to the conclusion ‘Some shirts are not red’. But if we consider
only statement I, then we find that it is the same as conclusion I.
5. D. A + I = No conclusion.
6. B. The word ‘only’ makes the first argument weak.
7. C.
8. C.
9. A. The failures of experiment initiates steps to rectify the mistakes in the
privatisation
10. B. The situation may not be the same in all countries makes argument I weaker.
