Question

the ratio of the age of p and q before 5 years is 7:9 after 10 years ratio will be 5:6then find the present ratio of p and q?​

Answer 1

Answer:

let the ratio of age of P and q is x/y

Step-by-step explanation:

before 5 years

p-5/q-5 = 7/9

9p-45 = 7q-35

9p-7q =-35+45

9p-7q=10. -eq(1)

after 10 years

p+5/q+5 =5/6

6p+30 = 5q+25

6p-5q =25-30

7p-5q =-5. -eq(2)

solving both equations
