(2) The units digit of 1,000*d is 7.



Statement 1:

If the tenths digit of 100*d is 7 the resulting number d would be something like xx.7xxx. This means if we do not multiply 100 to d the original number would be xx.xx7 (multiplying 100 to the original number shifts the number 7 two places to the right in the tenths place)
Hence this statement is sufficient.

Statement 2:

If the unitss digit of 1000*d is 7 the resulting number d would be something like x7.xxx. This means if we do not multiply 1000 to d the original number would be xx.xx7 (multiplying 1000 to the original number shifts the number 7 three places to the right in the units place)
Hence this statement is sufficient.

Answer: (D)
