**Answer: 162.**

Aakash hid 54, leaving 108. Bhavesh hid 36, leaving 72. Himanshu hid 24, leaving 48. 48 apples were then available to share in the morning.

To work these numbers out, we start at the end and work backwards.

At the end there were 16 apples each, therefore there were 48 apples.

Charles removed 1÷3 leaving 48, so there must have been 72 apples before he did this.

Bhavesh removed 1÷3 leaving 72, so there must have been 108 apples before he did this.

Aakash removed 1÷3 leaving 108, so there must have been 162 apples before he did this.
