Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 10% increase.
We can simply solve it using the net effect
Net effect = x + y + xy/100
here,
⇒ x = + 25 [increment]
⇒ y = - 12 [decrement]
So,
Net effect = 25 - 12 - 300/100
⇒ 13 - 3 = 10 [value is positive, it shows increament]
Thus,
10% increment will be seen in his salary
