Answer 1

Answer:

3 number question

Let the numbers be x and y.

x=4y …(1)

(21+x)/(y+21) = 7/4 or

4(21+x) = 7(y+21) or

84 + 4x = 7y +147, or

4x-7y = 147–84=63 …(2)

Put the value of x from (1) in (2)

16y–7y = 9y = 63, or

y = 7 and x = 28.

Check: (28+21):(7+21)::49/28 or 7/4. Correct.

The numbers are 28 and 7.
