spookyjaransh:
ya, thanx.........i was trying to get the total of 257 :-[ :-[ :-[ :-[ :-[ (not intentionally, just a little worked out now...), so thats wat was sooo confusing........ :P :P :P :P :P :P

holychalice:
heyy .. so hw did u do ?? hit and trial ?? or by sum formula ...
can sum1 confirm this answer ... cuz i think it cud be done graphically
is this a correct method ??

nid404:
no graph required......it has got to be using factors.

no graph for a 2mark question

wassup:
can ne1 explain me d b part???

nid404:
square root of 357 is 18.89....but there can't be fraction of bulbs....In the square number of rows and bulbs will be same...hence u take root...hope u got that... So the answer would be 18...the nearest whole number lesser than the number...it can't be 19 cuz 192>357
