Question 140

In a three digit number, the digit in the units place is 75% of the digit in the ten’s place. The digit in the ten’s place is greater than the digit in the hundred’s place by 1. If the sum of the digits in the ten’s place and the hundred’s place is 15, what is the number.

Solution

Since the digit in the unit's place is 75% of the digit in the ten's place, the only possibilities are 86, 43.

So, the two possible numbers are 786 and 343.

Since the sum of the digits in the ten's place and hundred's place is 15, the only possible number is 786.
