Q. The integers from 1 to 1484 are entered sequentially in 15 columns (numbered 1 to 15); i.e. Row 1 contains the numbers 1 to 15, Row 2 contains the next 15 numbers and so on. If the number 851 occurs in row p and column q, then the value of p + q is

• Ans 68
  851/15 quotient = 56 and remainder = 11
  => 851 is the 11th element after the end of 56 rows.
  Therefore 851 occurs in row. 57 and column. 11
  Therefore p+q = 68.

• p+q=68
  row will be (Quotient +1) and the column will be the remainder
  so row is 56+1=57 & remainder is 11 so ans is 68

• 68 is the right answer.

• when 851/15 then q=56 r=11
  no. of rows =q+1=56+1=57
  11th column contains last element

• 77
  851/15=56.7333
  p=56
  q=.7333*15
  p+q=67
