A. 94
B. 90
C. 75.6
D. 21.6
E. 14

Answer 1

B. 90

Explanation:

Let x be the original number.

We know that the number is decreased by 40%, which means we need to subtract 40% of the original number from the original number:

x - 0.4x = 54

Simplifying this equation, we get:

0.6x = 54

Dividing both sides by 0.6, we get:

x = 90

Therefore, the original number is 90.

So, the answer is B) 90.
