7. Two numbers are in the ratio 4:5 and their difference is 12. Find the numbers.


8. Two numbers are in the ratio 6 : 7. If their sum is 52, find the numbers.​

Answer 1

Answer:

7. Let the ratio of the numbers be 4x and 5x respectively.

according to your question,

5x - 4x = 12

or x = 12

Therefore, the first no. = 4x = 4×12=48

& the second no. = 5x = 5×12 = 60

8. Let the ratio of the numbers be 6x and 7x respectively.

according to question,

6x + 7x = 52

or 13x = 52

or x = 52/13

or x = 4

Therefore, the 1st no. = 6x = 6×4 = 24.

& 2nd no. = 7x = 7×4 = 28.
