The average temperature of Monday, Tuesday, and Wednesday was 41 degrees, and of Tuesday, Wednesday and
Thursday was 40 degrees. If on Thursday, it was exactly 39 degrees, then what was the temperature on Monday?​

Answer 1

Answer:

42 degree

Step-by-step explanation:

let the temperature on Monday be x

as per question

average temperature of Monday Tuesday and Wednesday is 41

so, x+tem.of Tuesday +tem.of Wednesday ÷3=41 .................eq.1

and, tem.of Tuesday +tem.of Wednesday +39 ÷3=40

Tuesday + Wednesday+39 =40×3

Tuesday +Wednesday +39=120

Tuesday +Wednesday =120-39= 81 ..........eq2

now putting value of eq 2 n eq 1

we get,

x+81 ÷3=41

x+81=41×3

x+81=123

x=123-81

x=42

temperature on Monday is 42 degree
