X rounded to tens place is 20. ( X > 15 and we want to round to tens place)
X rounded to the nearest tenth is 15.2 ( 15.246 rounded up)

So 20 * 15.2 = 304

Hence Option (D) is our answer.

Best,
Gladi

Hi Bunuel, I hope you're having a pleasant day. Could you please clarify if the OA above is correct? Shouldn't 15.246 rounded to the nearest tenth be 15.3 as 6 can round up 4 to 5 and 5 can round up 2 to 3, leaving the nearest tenth as 15.3, or are we just going to ignore all the numbers before 4? Please help my understanding here. Thanks

15.246 rounded to the nearest tenth is 15.2. You should take into the account only the first dropped digit. So, rounding is not cumulative.

Rounding is simplifying a number to a certain place value. To round the decimal drop the extra decimal places, and if the first dropped digit is 5 or greater, ROUND UP the last digit that you keep. If the first dropped digit is 4 or smaller, ROUND DOWN (keep the same) the last digit that you keep.

Example:
5.3485 rounded to the nearest tenth = 5.3, since the dropped 4 is less than 5.
5.3485 rounded to the nearest hundredth = 5.35, since the dropped 8 is greater than 5.
5.3485 rounded to the nearest thousandth = 5.349, since the dropped 5 is equal to 5.

So, according to the above 8.35y rounded to the nearest tenth will be 8.4 irrespective of the value of y.
