how did u get this answer?
So only possible number is 1 6 2 4 5 3
Can you explain how you got this answer.....................
According to me it is 408..................................................
Hi,
Can you explain Q.1,3 and 4....................
How did you get the number as 249?
In question 1 is there any twist????????
great pic of lingaraj temple......................
q4-8 what about 126453,243651,321654 apart from your answer.....................162453.
I was also wandering where I m lost. .
Q1. Consider a chessboard of size 16 x 16 (instead of the standard 8 x 8), what is the total number of squares on such a chessboard?
a. 256 b. 408 c. 1396 d. 1496
ANS: The chess board will have sq of 1 x 1 , 2x2 , 3x3,......., 16x16
Hence total sq = 12 + 22 + 32 + ......................+ 162 = 1496
Q4. A number when divided by 11, 7 and 4 leaves respective remainders of 7, 4 and 1. Instead, if the number is successively divided by 4, 7 and 11, what is the reminder in the division by 7?
a. 4 b. 3 c. 7
Use "CHINESE REMAINDER THEOREM" to get the ans as 4 (NO- 249)
