Option Observation - Need Clarity

#1
Hi All,

Today while I was having a look at options prices of one stock, thie was what happened -

eg -

500 stike CA, there is buyer at 30 Rs.

480 strike, there is buyer at 35 Rs.

460, there is seller at 42 Rs.

so 460 strike CA looks cheaper to me but still, people were buying 500 strike call ...

like the 460 strike call with premium becomes 502 and 500 strike with premium becomes 530 ... so why were people going for 500 strike call?? and there was more volume also in 500 waala call...

can someone pls explain ...
