tues+wed+thurs=111...(1)
wed+thurs+fri/3=38
wed+thurs+fri=114...(2)
and it is given friday is 39..
then wed+thurs=75

- tues+wed+thur=37*3
wed+thur+fri=38*3 (as avg of 3nos. thats why multiplied by 3)
(wed+thur+fri)-(tues+wed+thur)=(38-37)*3
fri-tues=3
tues=fri-3=39-3=36 - 11 years agoHelpfull: Yes(0) No(0)
- ans is 36 degree

(tue+wed+thr)/3=37
(tue+wed+thr)=111
similerly
wed+thr+fri=114
hence
fri-tue=3
39-tue=3
tue=36
