Answer:
B
Step-by-step explanation:
B. 48
9/12 must equal the x/64. 64/12 is 5.33333 repeating so multiply 9 x 5.33333 repeating would equal to 48
Let the original number be x.
Acc. to the question,
2x+1616=(2/5)x
or, 10x+8080=2x
or, 10x-2x= -8080
or, 8x= -8080
or, x= -8080/8
or, x = -1010
Therefore, the original number is -1010
