no sir..didnt check till 2800m...I thought that at 1100mts..they reach the initial position..but i guess yahan par galti ki hai..at 2200mts..they both will travel 800 and 1400 mts respectively...getting them back to initial position..at 1100 mts , they have traveled 400 and 700...so only one person is on his initial position..and the other 700 mts is at the opposite end..i.e. both are at the same point...ab bhi kuch galat hai kya??
i think this is right as the total distance travelled should be an even multiple of the distance.. also this is my logic as the difference between the distance travelled is 600 which implies there has to be 6*100 i.e 6 different meeting points on this hundred meter length. though i would like sir to explain the logic he was looking for
How many three digit perfect squares are there in base-7?
please give explanation

Usha bought a certain no of chocoltes at the rate of 16 chocolates for Rs 12 and the same no of chocolates at the rate of 24 chocolates for Rs 20. She sold all of them at the rate of 30 chocolates for RS 30. Find her gain/loss %.
25% gain hai kya?
@bodhi_vriksha
sir where did you disappear? waiting for the correct logic..

2nd ka ans 16!!!
@saurav205 Suppose Nimai starts from point A and Nitai from point B. After travelling 400 mts Nimai is back at A but after travelling 700 mts Nitai is not at B or his initial position, but at A. According to me, they can never simultaneously reach their initial positions.
Could you please point out where am I missing it ?

If Ram sold an article at four-fifth of its actual SP, he would have incurred a loss of 40%. FInd his actual profit/loss %.

( 3/4 + 5/6 )x=19x/12=CP
SP=2x
2-19/12 / 19/12 =5/19 *100=26.31?

Please refer to the earlier post...I have corrected it..
they will meet after travelling 2200 mts..
at 2200 mts together they would have traveled 800 and 1400 respectively..:)
wait for sir to put up the logic..this is just my take...

1/4 SP = 2/5 CP
SP=8/5CP

3/5 =60%?
