A can take values 1 to 9, B & D can take values 0 to 9. So, 3 gets printed in the 100’s place 900 times. A can take values 1 to 9, C & D can take values 0 to 9. So, 3 gets printed in the 100’s place 1000 times. B can take values 0 to 9, C can take values 0 to 9, D can take values 0 to 9. 3 can be printed in the 1000’s place, 100’s place or 10’s place or units place. So, 3 gets printed 280 times in 3-digit numbersįour-digit numbers: A B C D. So, 3 gets printed in the unit’s place 90 times A can take values 1 to 9, B can take values 0 to 9. So, 3 gets printed in the 10’s place 90 times A can take values 1 to 9, C can take values 0 to 9. ![]() So, 3 gets printed in the 100’s place 100 times B can take values 0 to 9, C can take values 0 to 9. 3 can be printed in the 100’s place or 10’s place or units place. We need to consider all three digit and all 4-digit numbers. This question is based on counting the number of times a particular digit appears in a list.

We have any one of five choices for the first digit, but then for the next two digits we have four choices since we are not allowed to repeat the previous digit So there are \(5 \cdot 4\cdot 4 = 80\) possible different three-digit numbers if only non-consecutive repetitions are allowed.Question 1 Question 2 Question 3 Question 4 Question 5 Question 6 Question 7 Question 8 Question 9 Question 10 Question 11 Question 12 Question 13 Question 14 Question 15 Question 16 Question 17 Question 18 Question 19 Question 20 Question 21 Question 22 Question 23 Question 24 Question 25 Question 26 Question 27 Question 28 Question 29 Question 30 Question 31 Question 32 Question 33 HCF and LCM Factors Remainders Factorials Digits Ratios,Mixtures Averages Percents Profits SICI Speed & Time Races Logarithms and Exponents Pipes,Cisterns Work,Time Set Theory Geometry Coordinate Geometry Mensuration Trigonometry Linear & Quadratic Equations Functions Inequalities Polynomials Progressions Solution to (c): Again, the rule of products applies here. So there are \(5 \cdot 5\cdot 5 = 125\) possible different three-digit numbers if repetition is allowed. ![]() We have any one of five choices for the first digit, five choices for the second, and five for the third. However, the rule of products still applies. Solution to (b): The definition of permutation indicates “.no two elements in each list are the same.” Hence the permutation formula cannot be used. 600 PERMUTE 3 HOW TO 600 PERMUTE 3 CODE 11:10:45,875 - INFO - Writing partition 1, shard 0 11:10:45,875 - INFO. ![]()
