Let us assume that the price of coat in children size is c and price of coat in adults' sizes is a.

According to #1:
a+c=230--------> Not sufficient

According to #2:
2a+c=370-------> Not sufficient

Combining statement 1 and 2, we have a system of 2 equations and 2 variables.
We can solve for the value of a now.
