Question

0.4. A positive number is 7 times another number. If 15 is added to both the numbers,
then one of the new number becomes 5/2
times the other new number. What are the
numbers?
please help​

Answer 1

Answer:

x + 15 = 5 2(+15) .7

5x 2(x + 15) + 5 x 15 7 2x + 30 = 5x 7 + 75

On simplification we get,

5 2x -X= 75 - 30 7

14 - 5 7 x = 45

9x 7 =45

x= 45 x 7 9

We get,

x= 35

Hence,

One number = 35

35

Other number = = 5

7

Therefore, the numbers are 35 and 5
