[00:00:00]Hello viewers, I'm Maithili.

[00:00:08]Gopal is 8 years younger to Karnan.

[00:00:14]If the sum of their ages is 30, how old is Karnan?

[00:00:34]Let Gopal's age be X.

[00:00:47]Karnan is Y.

[00:00:49]Equal.

[00:00:50]Equal.

[00:00:59]X is equal to 8 years younger to Karnan.

[00:01:14]8 less So, Karnan's age is Gopal's is equal to put on 8 years younger to Karnan.

[00:01:36]If the sum of their ages is 30 Sum of their ages is 30.

[00:01:51]So, you add equal to 30.

[00:01:53]So, X plus Y is equal to 30. You write it down.

[00:01:58]>> equal to 30 y minus 8 plus y is 30 x is equal to y minus x and y y minus 8 y minus 30 y plus y like terms like terms like add them y up here put number add them number one one number one plus one two and I don't two y minus 8 is equal to 30 number variable number variable number 8 number plus two number minus number plus 8 I don't number two 30 plus 38 y number y or two number number number number number number number number number number number number number number number 38 divided by two two ones remainder two nines are 18 zero y is equal to 19 Karnan is 19 years old.
