X.

sixth parts of a certain number exceeds the difference of its sixth and ninth parts by 16. Find the number.

  1. There are two consecutive numbers, x and x+1, such that one-half the larger exceeds one-third the smaller number by 10. Find the numbers.

Exercise 56.

Ex. The sum of two numbers is 63, and if the greater is divided by the smaller number, the quotient is 2 and the remainder 3. Find the numbers.

lint Let x = the greater number. lint Then 63 - x = the smaller number. Since the quotient = Dividend - RemainderDivisor,

and since, in this problem, the dividend is x, the remainder is 3, and the divisor is 63x, we have

x - 363 - x = 2. lint Solving, x = 43.

The two numbers, therefore, are 43 and 20.

  1. The sum of two numbers is 100, and if the greater is divided by the smaller number, the quotient is 4 and the remainder 5. Find the numbers.
