dheeraj  (8 years ago)

ans is 1

as there r only 3 squares b/w 2006-2300 that are 45^2=2205, 46^2=2116, 47^2=2209
now this series is an ap with 7 differnce.
so the difference of these squares & 2006 must be a multiple of 7.
only 2209-2006=203 which is multiple of 7.
so correct ans is 1.

As the question is given in the A.P.so the common difference is 7 and first value is 2006.so we can write 2006+7K,
45^2=1936+(2*45-1)=2025 (or,45^2=2025)
46^2=2025+(2*46-1)=2116 (or,46^2=2116)
47^2=2116+(2*47-1)=2209 (or,47^2=2209)
in this question last value is 2300 .so we can not write 23^2.

so, in this only 3 squares term are present so answer will be 3.
