the age of rahul and harun is 5:7. After four years, Sum of their age is 56. What is their present age?

20 and 28

Step-by-step explanation:

r/h= 5/7  ⇒ r= 5/7h

r+4+h+4= 56

r+h= 48

5/7h+h= 48

12/7h=48

h= 28

r= 48-h= 20

Rahul is 20, Harun is 28

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
