give the ans plz.....................................

Answer 1

let sugar level of seventh day be x

SO average of seven days is to be 130

so
(142+131+113+110+148+139+x)/7 = 130
783 + x = 910

x = 127

so required sugar level at seventh day = 127

Answer 2

Hey

First day = 142

Second day = 131

Third day = 113

Fourth day = 110

Fifth day = 148

Sixth day = 139

Let seventh day be x .


So ,

mean average =

sum of all days / number of days


=> 142 + 131 + 113 + 110 + 148 + 139 + x / 7 = 130

=> 783 + x = 910

=> x = 910 - 783

=> x = 127
