39 and 48
IF we use four different digits ,For example 12 , 35. 98. 72 . when we add two 2 -digits numbers. 12 + 35 =47 98 + 72 =160 72 + 35 = 107 98 + 12 = 110 the least sum we can get 12+ 35 = 47.
This happens because the contribution of the smaller number is lost in the trailing decimal digits. Suppose you had a calculator that could display 10 digits. Suppose you tried to add 123,456.789 and 0.000 000 12 The true answer is 123,456.789 000 12 but, since you can only display 10 digits, the answer shows as 123,456.7890 which is the larger number. The exact details will depend on the number of displayed digits.
You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point. Thus (assuming the "short scale") you get: 53,620,000,000.You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point. Thus (assuming the "short scale") you get: 53,620,000,000.You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point.

Numbers below 100 which can be divided equally between 3 and 4 are:12, 24, 36, 48, 60, 72, 84, 96Therefore, the two-digit number whose digits add up to 15 and which shares 3 and 4 as common factors is 96.
Calculating the average of the two numbers gives you the answer. (Add the two numbers, then divide the result by 2.)

33 and 39The way to do this is to see which odd numbers between 30 and 40 have digits that add up to a multiple of 3 since this is the test to see if a number is divisible by 3.So 33 has digits that add to 6 since 3+3=6 and 33 is oddAlso, 39 has digits that add up to 12 since 3+=12 and 39 is odd.36 has digits that add to 9, but it is even so we discard it.

All numbers that are divisible by 6 are even numbers whose digits add up to 3 or a multiple of 3. Example : 284 is not wholly divisible by 6 as although it is even, its digits total 2 + 8 + 4 = 14 which is not divisible by 3. 282 is divisible by 6 as it is even and its digits total 12 which is divisible by 3.
there are 12 numbers for billion
The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
Numbers below 100 which can be divided equally between 3 and 4 are:12, 24, 36, 48, 60, 72, 84, 96Therefore, the two-digit number whose digits add up to 15 and which shares 3 and 4 as common factors is 96.
