Answer 1

Answer:

77/240

Explanation

According to question , formula of taking out mean =sum of all observations/number of observation =1/2+1/3+1/4+1/5 /4 = taking out LCM = LCM of 1/2+1/3+1/4+1/5 is 60 =30+20+15+12 =77 = by adding 30+20+15+13 and 4 ,× 60 = 240 and then dividing 77 /240we will get the answer

= ANSWER=77/240
