Correct Option: A
Given that , The average temperature for Monday, Tuesday, Wednesday and Thursday = 48°
Monday + Tuesday + Wednesday + Thursday = 4 × 48° = 192° ..... (i)
The average temperature for Tuesday, Wednesday, Thursday and Friday = 52°
Tuesday + Wednesday + Thursday + Friday = 4 × 52° = 208° ..... (ii)
By equation (ii) – (i),
Friday – Monday = 208° – 192° = 16
⇒ Friday = 16 + 42 = 58°
