Direction for the following 3 (three) items: Consider the given -formation and answer the three items that follow.
Six boxes A, B, C, D, E and F have been painted with six different colours viz., violet, indigo, blue, green, yellow and orange and arranged from left to right (not necessarily either kept or painted with the colours in the same order). Each box contains a ball of any one of the following six games: cricket, hockey, tennis, golf, football and volleyball (not necessarily in the same order). The golf ball is in violet box and is not in the box D. The box A which contains tennis ball is orange in colour and is at the extreme right. The hockey ball is neither in box D nor in box E. The box C having cricket ball is painted green. The hockey ball is neither in the box painted blue nor in the box painted yellow. The box C is fifth from right and next to box B. The box B contains volleyball. The box containing the hockey ball is between the boxes containing golf ball and volleyball.
74. Which one of the following boxes contains the golf ball?
(d) None of the above
Sol. Ans (b)
Given six boxes A, B, C, D, E and F.
Colours are violet, indigo, blue, green, yellow and orange (not in order).
Kept from left to right (not in same order).
Six balls of cricket, hockey, tennis, gold, football and volleyball (not in same order).
As per the given information, we can try and make either an elaborate grid, and place values one by one (values will be mostly ticks and crosses initially). Positions are 1,2,3,4,5,6 from L to R.
After a few iterations, we will arrive at the answers. Or else we can simply read through the questions and realize that it is not worth the effort as elimination may be possible. Make simple relations like these.
Ball = Colour = Box = Position
Golf = Violet = Not D = . .....(1)
Tennis = Box A = Orange = 6 (full information given) .....(2)
Hockey= . = Not D, Not E = . .....(3)
Cricket = Green = Box C =. .....(4)
Hockey = NotBlue, Not Yellow = . =. .....(5)
.= .= BoxC = 2 .....(6)
Volleyball = . = Box B =. .....(7)
Now, C is next to B. So B can be 1 or 3. Let us put that in (7) to get
Now, hockey is between golf and volleyball. So apply (5), (1) and (7’) together to get
Box B – Hockey – Violet
Eliminate the known variables and you can easily find out that the Golf ball is in Box B. Also, Box F is painted indigo. And two possibilities remain for the colour of Box containing football, hence indeterminate.
