Question

solve 3rd numbers please.

Answer 1

3) given,

The temperature on Tuesday = 89°C

let temperature on Sunday be x.

temperature on Monday be y.

temperature on Saturday be z.

Average of temperature on Sunday, Monday and Tuesday = 85°C

=> Temp.(Sunday)+Temp.(Monday)+Temp.(Tuesday)/3 = 85°C

=> x+y+89°C/3=85°C

=> x+y+89=255

=> x+y=166°C...............(1)

Average of temperature on Sunday, Monday and Saturday = 82°C

=> Temp.(Sunday)+Temp.(Monday)+Temp.(Saturday) = 82°C

=> x+y+z/3 =82°C

=> 166+z/3=82

=> 166+z=246

=> z=80°C

The temperature on Saturday is 80°C
