TCS (Tata Consultancy Service) Commonly Asked Interview Puzzles - Here in this video, some of the important puzzle patterns are shared which are frequently asked in TCS Job Interviews.
The 17 horses problem was solved by me by finding lowest common denominator for the 3 fractions and then comparing equivalent fractions to see the ratio and it worked out perfectly as to how many horses went to each son.
Hi @Simply Logical, In the problem where John Earns 1$ on Day 1, 4$ on Day 2 and 7$ on Day 3 and So on....The question is "What is John's earning on Day 1001", Not the sum of all earnings from Day 1 to Day 1001.... His earning on Day 1001 is the 1001th Term in the progression, which is Tn = (a + (n-1)d). Substituting a =1, n = 1001, and d = 3, we get 3001. Another way to look at it, if you want to verify John's earning on Day 3, using your formula of S=1/2(2a+(n-1)d)n, we will get 12, which is the sum of all earnings from day 1 to day 3 and not the earnings on Day 3 itself! So as explained above, according to me, the correct answer for John's earning on Day 1001 must be 3001.
