For Paper 2 question 5 the answer is 325
There are total 18 bulbs distributed along the perimeter of a rectangular field. There are 5 bulbs on one side of the field out of which 2 bulbs are on the two corners of the field. What is the length of the field?
Since there are 5 bulbs there are 4 intervals. Each interval is 260/4 = 65.
On one side of the breadth there are 5 similarly there will be another 5 on the opposite breadth. This is a total of 10 bulbs. There are 8 bulbs (18-10) to be distributed across the remaining "two sides" of the length. That would be 4 each on each side. 8/2 =4
There would be 5 intervals on each side of the length. 5 * 65 = 325
Alternatively, if you don’t distribute the remaining 8 bulbs on both sides there will be 9 intervals and the length would be 9*65 = 525
I think the answer is 325 and not 525. -
However, it is not both sides of length that are filled only 2 breadth and 1 length

Lurline, I dare not show DS this website... else I will have heart attack :stompfeet:
He already told me he has 10 marks deducted for careless which he detected... -
Is the question where answer is Wednesday in paper 1 or 2 and how many marks?
-
I did not check with my DD if her math answers tally with those posted here. I am :xedfingers: that she will do well enough to compensate the marks she lost in the EL papers. I did not even check her EL answers against those posted online, which I still have no guts to click. Just the few questions that she raised for clarification, her answers were all incorrect. That sent me :faint:
:nailbite: . I do not want to go through it again. -

In the question it says the bulbs are distributed around the perimeter of rectangular field even though the figure shows bulbs on one side of the length to give a view of how they are put.. on the length it shows \".............\" to illustrate the figure
How can the bulbs will be put on only two breadths and on one length while showing the whole rectangle?
believe this is the trap.. -
Me too. I did not check her answers for EL and Math. I will not check the rest too. I just ask her if is difficult…
I believe she had done her best. -

No the question said that the bulbs were distributed evenly along THREE sides BC, CD, AD. Lolz big big trap for allRandomperson21:
