Option 4 : 16.1

**Given: **

Average of 9 numbers wrongly calculated = 15

**Formula Used:**

Average = Sum of all items / Number of items

**Calculation:**

Average = Sum of all items / Number of items

⇒ 15 = Sum of 9 numbers/9

⇒ 135 = Sum of 9 numbers

Correction

⇒ 135 + 46 - 36 = 145

New average = 145/9 = 16.1

∴ Corrected average of 9 numbers is 16.1

The correct option is 4 i.e. 16.1
