A philatelist is a person who collects stamps while a numismatist is a person who collects coins as a hobby. 4. A taxidermist is a person who engages in stuffing dead animals and preserving them while the other three are types of doctors 6. The average income for the given period is (70+60+85+90+75)/5 = 76 crores. Now, the income in 2006 is 90 crores and the income in 2005 is 85, which are both greater than 76 crores. 8. 5 + 4 = 9, 3 + 9 = 12, 5 + 12 = 17. Therefore, the last number is 9 + 17 = 26 9. G(5) = G(4) – G(3) = G(3) – G(2) – G(3) = -G(2) = -(G(1) – G(0)) = -(1-(-1)) = -2 10. The fraction of work done by A, B and C together in 1 hr = 1/total time = 1/3rd. Hence, remaining work = 1-1/3 = 2/3 . Now, this 2/rd of the work is done by A and B (as C leaves) in 7/2 hrs. Hence time taken by A and B to complete total work = 7/2 x (1/(2/3)) = 7/2 x 3/2 = 21/4 hrs. Thus we have the equation; (1/C + 1/(A+B)) = 1/3, where C is the time taken by C alone to do the job, (A+B) represents the time taken by A and B to do the total job. We know A+B = 21/4, thus we get C = 7 hrs. Alternate Method: Let a, b and c be the rates or speeds of doing work for A, B and C respectively. The first step is to calculate the LCM of all the “times” given in the question ie 3 hrs and 3.5 hrs. The LCM is 21. Let us now assume the total work to be 21 units (this assumption will not make any diff in the final answer). Now, A, B and C working together take 3 hrs to finish 21 units. Therefore the total rate of working when they work together = Total work/total time taken = 21/3 = 7 units/hr. In other words, a +b + c = 7. Now, in the first 1 hr, all three work together. Thus they will Hence, remaining work units = 21-7 = 14. These 14 units are completed by A and B in 3.5 hrs. Thus, total rate of working for A and B together = a + b = Work units/ time taken = From this, we get c = 7 – 4 = 3 units/hr. Therefore, time taken by C to complete the total work alone = Total work units/ rate of working for C = 21/c = 21/3 = 7 hrs.
