The amount of 120000 should be deposit in X account in the bank as it is giving more amount of compound interest.
As given in the question we have two accounts that is X and Y.
In X account the rate of interest is 8% per annum semi annually compound interest which means 16% per annum for year.
In Y accounts the rate of interest is 12% per annum compound interest for year.
hence, if we deposit the Rs. 120000 in bank with account X then
120000×16%= 19200 [ first year interest]
139200×16%=22272[second-year interest]
the total amount of compound interest = Rs 41472.
now if we deposit in Y account then
120000×12%=14400
134400×12%=16128
the total amount of compound interest =Rs 30528
now we can see that we are getting more interest amounts in X account compared to Y.
hence, depositing the Rs.120000 in account X will be beneficial.
