anandhi  (8 years ago) Best Solution

Amount left = 0.5x−4
For fifth store this is zero. So x = 8. That means he entered fifth store with 8.
Now for fourth store, amount left = 8 so 0.5x−4=8⇒ x = 24
For third store, amount left = 24 so 12x−4=24⇒ x = 56
For Second store, amount left = 56 so 0.5x−4=56⇒ x = 120
For first store, amount left = 120 so 0.5x−4=120⇒ x = 248
So he entered first store with 248.

As he has spent all his money, He must spend Rs.8 in the final store.
a simple equation works like this. Amount left = 1/2x−4
For fifth store this is zero. So x = 8. That means he entered fifth store with 8.
Now for fourth store, amount left = 8 so 1/2x−4=8⇒ x = 24
For third store, amount left = 24 so 1/2x−4=24⇒ x = 56
For Second store, amount left = 56 so 1/2x−4=56⇒ x = 120
For first store, amount left = 120 so 12/x−4=120⇒ x = 248
So he entered first store with 248.
