+## Practice Problem 47 ( map(), filter(), find() )
+
+1. You have **an odd array (array with odd numbers). [ 1, 3, 5, 7, 9 ].**
+Now convert this array **into an even array (array with even numbers). [ 2, 4, 6, 8, 10 ].** 
+Do this using `for loop` & `array.map()`
+method. Hints: add one to any odd number and it will become an even
+number.
+
+2. You are given **an array say: [33, 50, 79, 78, 90, 101, 30 ]**. Now
+return/get all the elements which are divisible by 10 using
+`array.filter()` method.
+
+3. Now do the **same task of question 2.** But do this using `array.find()`
+method. Then **compare the output** of question 2 & question 3.
