Question

One number is 4 more than another, and their sum is 60. What is the smaller number?

26
28
32

Answer 1

28, because 28+32 is 60

Answer 2

option B. 28

Explanation:

Let the numbers are x and y.

One number is 4 more than another.

so equation will be x = y + 4 --------(1)

sum of both number is 60.

so x + y = 60 ---------------(2)

By replacing x from equation (1) to equation (2)

y + 4 + y = 60

2y + 4 = 60

2y = 60 - 4 = 56

y = 28

Therefore, smaller number is 28 given in option B.
