Kumar spent $1729 on a set of encyclopedia. H spent 1/4 of the remainder on a camera and still had 2/5 of his money left. Find the total amount of money he had at first.
Solution
3/5 of money --> $1729 + 1 unit
(multiply above by 3)
9/5 of money --> $5187 + 3 units
2/5 of money --> 3 units
9/5 - 2/5 --> $5187 + 3 units - 3 units
7/5 --> $5187
1/5 --> $5187 divided by 7 = $741
5/5 --> 5 x $751 = $3705
Answer: $3705
