Answer:
120 * (1 + d/100) * 1.25
Explanation:
Increase 120 by "d%": 120 * (1 + d/100)
Here, (1 + d/100) represents the factor by which we increase 120 based on the percentage "d".
Increase the above result by 25%: 120 * (1 + d/100) * 1.25
Here, we multiply the previous result by 1.25 to increase it by 25%.
So, the expression 120 * (1 + d/100) * 1.25 will give you the result after increasing 120 by "d%" and then increasing the result by 25%.
