Let the temperature of Monday, Tuesday, Wednesday be x degree celsius, y degree celsius and z degree celsius respectively

The temperature of Thursday is 4/5 * x degree celsius

The average of the temperatures of Monday, Tuesday, Wednesday gives us

(x +y + z)/3 = 37

The average of the temperatures of Tuesday, Wednesday, Thursday gives us

(y + z + 4/5 x) /3= 34

We get

(x +y + z) = 37 * 3

y + z = (37 * 3) -x

using the value of y+z in the second equation we get

(37 * 3) -x + 4/5 x = 34 *3

(37 * 3) – (34 * 3) = x – 4/5 x

3 ( 37-34) = 1/5x

9= 1/5 x

x = 45

The temperature on Monday is 45 degree celsius

The temperature on Thursday is 4/5x = 4/5 * 45 = 36 degree celsius
