Answer: (3). Rs. 2400

The Rupees spends in first four months of year = 1800.
let salary of first four months be X,
Average salary of first four months = total salary of first four months / 4 months
1800 = X / 4
X = 1800 * 4
X = 7200. a total salary of first four months is Rs. 7200.

The Rupees spends in next eight months = 2000.
let salary of next eight months be Y,
Average salary of next eight months = total salary of next eight months / 8 months
2000 = Y / 8
Y = 2000 * 8
Y = 16000, the total salary of next eight months is Rs. 44800.
and saving of year = Rs. 5600

Therefore, the total salary of the year = salary of first four months + salary of next eight months + saving of the year.
Total salary of year = Rs. ( 7200 +16000 +5600 )
A total salary of year = Rs. 28800
The average salary of year = 28800 / 12
Average = Rs. 2400.
