    Solution

    LetтАЩs assume that initial number of students be x. тИ┤ Number of toffees given to x students = 15x After the arrival of teacher and headmaster, total toffees distributed = 15x + 20 + 28 = 15x + 48 Now, the average becomes 18, тИ┤ 15x + 48 = 18 ├Ч (x + 2) тЗТ 15x + 48 = 18x + 36 тЗТ x = 4 тИ┤ The number of students among whom the toffees┬аwere distributed is 4.
