There is a lot of speculation that the economy of a country depends on how fast people spend their money in addition to how much they save. Auggie was very curious to test this theory.
Auggie spent all of his money in 5 stores. In each store, he spent Rs.4 more than one-half of what he had when he went in. How many rupees did Auggie have when he entered the first store?
a. 248 b. 120
c. 252 d. 250
Read Solution (Total 4)
-
- 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. - 9 years agoHelpfull: Yes(23) No(2)

- 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.
