Statement 1 is correct.  

Exports are cheaper to foreign customers: If the value of the rupee decreases against the dollar, the price of the cars sold by Indian manufacturers in America, in dollars, will be effectively less expensive than they were before. On the other hand, a more valuable currency makesexports relatively more expensive for purchase in foreign markets. 

Statement 2 and 3 are incorrect.  

Devaluation of a currency decreases the foreign value of domestic currency.
