So here the question is john took all of his money from his savings account and he spends 108 on a radio.
00:08
So yeah, the final question was how much money did john originally have in his savings account? so let's take let x be, he's writing, let x be the amount that he has, that he has originally in his account.
00:36
So we can take it as x as that original amount that he has in his savings account and it was told that one not eight she he spent on a radio so amount spent on amount spent on radio is equal to it is given as one note eight now the next thing given is and five out of nine parts of what left what was left to presence for his friend so now the money left will be equal to the money left with him will be equal to x minus 108 because x was the initial amount now one zero eight he paid on this radio now amount he will spend on presence to his friends amount spent on presence is given as five out of nine part that is 5 by 9 into the remaining money's x minus 108 this will be the amount spent on the presents for his friends now of them yeah next thing given is of the money remaining john put 5 by 6 into a checking account so now the money remaining will be equal to remaining money will be equal to so here i can tell x minus 108 was remaining money at this point of time.
02:28
So from that 5 by 9 part is spent.
02:32
So i can write x minus 108 minus 5 by 9 into x minus 108 and this will be equal to 4 by 9, 4 by 9 into x minus 108.
02:53
Oh directly we can tell money left was x minus 108.
02:57
So if we divide that to nine parts, five part is spent on the present.
03:01
So the remaining part will be four parts.
03:03
So this will be the remaining money.
03:06
And in this, five by six parts is spent into a checking account.
03:11
So to checking account, the money spent will be equal to five by six parts of the remaining money, that is five by six into four by nine into x minus one zero eight.
03:35
So i can write this is equal to 5 into 4 that is 20 or i can cut from here.
03:42
This will be 2.
03:44
This will be 3.
03:46
So 5 into 2 that is 10 10 divided by 3 into 9 that is 27.
03:51
So i can write this as 10 by 27 into x minus 108...
