Question

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

Step-by-step explanation:

Let the ratio be x

A/ Q

4x - 5x = 12

-x = 12

x = -12

4x = 4*-12=-48

-5x = -5*-12 = 60

Let the ratio be x

according to question

6x + 7x = 52

13x = 52

x=52/13

x=4

6x =6*4=24

7x=7*4=28

Answer 2

Answer:

The answer of question 7 is 48 and 60 and the answer of question 8 is 24 and 28.

Step-by-step explanation:

Ans7) Let the two numbers be 4x and 5x

Given, Difference = 12

By condition,

5x - 4x = 12 => x = 12

First number = 4x = 4×12 = 48

Second number = 5x = 5×12 = 60

Ans8) Let the two numbers be 6x and 7x

Given, Sum = 52

By condition,

6x + 7x = 52 => 13x = 52 => x = 52/13 = 4

First number = 6x = 6×4 = 24

Second number = 7x = 7×4 = 28
