6. Directions(6-10): The following questions are accompanied by three statements A, B and C. You have to determine which statement(s) is/are necessary/sufficient to answer the question.

7. What is the cost price of a table?
A. By selling the table for Rs. 600 instead of Rs. 500, loss per cent decreases by 10%.
B. When the cost price of the table increases by 10% and then decreases by 10%, it reduces by Rs.10.
C. By selling the table and a chair for Rs. 1500 a net profit of 25% is made.

Only C.
None of these.
Only B and C alone.
Only A or B alone.
All of these.
Option D
Let C.P. = x
From A: (x-1500)*100/x – (x-600)*100/x = 10
From B: 90/100*110/100x = x – 10
From C: Table + chair = 25 % profit

8. Find the number of pigs in a group of pigs and hens.
A. The total no. of hens is 20.
B. In the group, the no. of legs are 32 more than twice the no. of heads.
C. If 4 rabbits be included in the group, the total no. rises to 40.

Neither B nor C.
All of these.
Either B alone or A and C together are sufficient.
Only A or B.
Only A and B.
Option C
From A: h = 20
From B: 4P + 2h = 32 + (P + h)*2 P = 16
From C: h + P = 40 – 4 = 36, using A P = 36 – 20 = 16
So,either B alone or A and C together are sufficient.

9. A boat takes 2 hours to travel from point A to B in still water. To find out is speed upstream, which of the following information is/are required?
A. Distance between point A and B.
B. Time taken to travel downstream from B to A.
C. Speed of the stream of water.

Only A and B.
Any two of them are sufficient.
None of these.
Only B.
Either A or C only.
Option B
Let distance d.
speed in still water = x
speed of current = y
=> d/x = 2
From A: d given.
From B: d/(x+y) = given
From C: y = given
So, any of them together are sufficient.

10. A bag contains balls of only three different colours ie, red, yellow and green. 3 balls are drawn randomly. What is the probability that the balls drawn are of three different colours?
A. The no. of yellow balls is two more than the no. of red balls.
B. The Sum of the no. of yellow and green balls is three times the no. of red balls.
C. The ratio of the no. of red balls to that of green balls is 3 : 4.

Only B.
Only A and B.
Either B or C only.
All statements are required.
None of these.
Option D
From A: y = r + 2
From B: y + g = 3r
From C: r : g = 3 : 4
To determine the number of different colour bells , all statements are required

11. What will be the average of three numbers?
A. The largest no. is greater than the smallest by 20.
B. The sum of the largest and smallest nos. is equal to twice the middle one.
C. The difference of the first two numbers is 10.

None of these.
Only A.
Either B or C only.
Neither A nor C.
Only A and B.
Option A
Let largest no. = Z
Middle No. = Y
Smallest No. = X
From A: Z= X + 20
From B: X + Z = 2Y
From C: Y – X = 10
From all statements, we can’t determined the average value.
