Detailed Solution

Given that the increment in the salary is 10%.
Let the old salary be x and the new salary be y.
Calculating the new salary:
Using the variables of old salary and new salary in the percentage formula, we get,
New salary = old salary + 10% increment.

y = x + 10100 x y = 110100 x

Given new salary is (y) = Rs.1, 54,000.

x = 100110 y

Substituting the value of new salary in percentage formula,

x = 100110 × 154000

=140000
So, the old salary x is Rs.1,40,000.
Thus, the given statement is true.
Therefore, option 1 is correct.
