Is the hundredths digit of the decimal d greater than 5?

(1) The tenths digit of 10d is 7 (2) The thousandths digit of d/10 is 7

My question is are we supposed to think that when it is said decimal it in the form of 0.xyzabc....??? I want to know if i can say 1000.2394879324 a decimal....

Is the hundredth digit of decimal d greater than 5? 1. The 10th digit of 10d is 7 2. the thousandth digit of d/10 is 7

My question is are we supposed to think that when it is said decimal it in the form of 0.xyzabc....??? I want to know if i can say 1000.2394879324 a decimal....

Can someone clarify??

d can be any number, so it's not necessary to be of the form 0.12345, it can be 12345.12345 or any other real number in decimal representation. But for this particular question it really doesn't matter so we can take d to be a.bc (it does not matter how many numbers are before decimal point or after hundredth digit).

Is c>5?

(1) The tenths digit of 10d is 7 --> 10d=ab.c --> tenth digit of 10d is c, so c=7>5. Sufficient. (2) The thousandths digit of d/10 is 7 --> \frac{d}{10}=0.abc --> thousandth digit of \frac{10}{d} is c, so c=7>5. Sufficient.

Thanks bunuel, But what if the decimal d=72121.212121 d/10 = 7212.12121 in this case with statement 2, the thousands digit is 7 but that information is not enough to find out the hundredth digit... please correct me where i am wrong... Thank you very much for the reply

There is a difference between THOUSANDS and THOUSANDTHS.

you posted in 1234.567, 5 = 10 th digit. Will you please explain. Is it not unit digit ?

Thanks in advance. Regardsi

Nope. In 1234.567 the units digit is 4 (the first digit to the left of decimal point) and the tenths digit is 5 (the first digit to the right of decimal point). _________________
