To type the first 160 natural numbers, Ritika needs to press the numbered keys multiple times.

Step 1: Determine the range of numbers to be typed. In this case, it is the first 160 natural numbers.

Step 2: Calculate the number of digits in the range. The first 160 natural numbers have a maximum of 3 digits.

Step 3: Determine the number of times each digit needs to be pressed. Since there are 10 digits (0-9), each digit will be pressed 16 times (160 divided by 10).

Step 4: Multiply the number of times each digit needs to be pressed by the number of digits in the range. In this case, 16 times 3 equals 48.

Therefore, Ritika needs to press the numbered keys 48 times to type the first 160 natural numbers.
