The average temperature of Monday, Tuesday, Wednesday
and Thursday is 50°. The average temperature for Tuesday, Wednesday, Thursday and Friday is 60°. If the ratio of temperature for Monday and Friday is 1 : 5, then what is the temperature of Friday?Solution
ATQ: M + Tu + W + Th = 200°-----(1) Tu + W + Th + F = 240° ------(2) Subtracting eq 1 from 2 we get, F - M = 40° 5x - x = 40° x = 10° Therefore, temperature of Friday = 50°
