-
B.
0.1667
-
C.
0.3333

D.
0.1428
Correct Answer:
B. 0.1667
Explanation:
To find the value of x, first calculate the two base values. 40% of 70 is 28, and 30% of 80 is 24. The problem states that 28 is x% more than 24. The difference between these two values is 4. To find the percentage increase, divide this difference by the base value of 24 and multiply by 100. This calculation, 4 divided by 24, simplifies to 1/6, which is approximately 16.67%. Therefore, x is 16.67%.
