Answer» C.I different hai so you can solve through assume mean method instead of deviation method by assume mean method u can get answer easily Isme class size same kar lena lower limit mein .5 subtract kar dena aur upper limit mein .5 add kar dena isliye H 40 liya hai Because the distance between classinterval is 20 . h means height so h=20 Shyad misprinted h yha pe 40 aana chahiye |
