+# Multiply numeric properties by 2
+
+Create a function `multiplyNumeric(obj)` that multiplies all numeric properties of `obj` by `2`.
+
+For instance:
+
+```js
+// before the call
+let menu = {
+  width: 200,
+  height: 300,
+  title: "My menu"
+};
+
+multiplyNumeric(menu);
+
+// after the call
+menu = {
+  width: 400,
+  height: 600,
+  title: "My menu"
+};
+```
+
+Please note that `multiplyNumeric` does not need to return anything. It should modify the object in-place.
+
+P.S. Use `typeof` to check for a number here.
