Hi,

Pls help to solve this q.

Hanson had some one-dollar coins and some fifty cents coins. The ratio of the no of one dollar coins to the no

of fifty cents coins was 2:5.

Hanson took 140 fifty cents coins to he bank and changed for the same value of one dollar coins.

In the end, the no of one dollar coins to the no of fifty cents coins is 5:2.

Find the value of the fifty cents coins.

Ans $100.
