A certain sum was put on simple interest at 20% per annum for 2 years. Then the amount received after 2 years put on compound interest 12% per annum for 2 more years. If the amount received at the end of 4 years is 43904 Rs. Then find the amount invested at starting ?
(a) 20,000 Rs. (b) 25,000 Rs. (c) 30,000 Rs. (d) 40,000 Rs. (e) None of these
A,B,C can complete a work in 30 days by working together. A+C are twice efficient than B and A+B are thrice efficient than C. Find in how many days A alone can complete the work.
A alone would take 27 hours more to complete a work than A&B together. B takes 3 hrs. More to complete a work alone than A&B work together. In how many days A alone can do the work alone?

Work - Time some patterns:
⚡Actual/Scheduled days⚡
1. A can complete a work in 3 3/4 days while B can complete it in 4 1/6 days. They together started working on it. In how many,days was the work completed if B left 1 1/2 days before the ACTUAL COMPLETION of the work?
2. A takes 20 days and B takes 25 days to complete a work. They started working together. B left 1 day before SCHEDULED COMPLETION of work. In how many days was the work completed?
⚡Efficiency related⚡
1. A takes 8 days to complete a work alone. B is 20 percentage more efficient than A. A works for 2 days first, then B works 1 day amd the cycle repeats. In how many days would the work be completed?
2. A and B working together can complete a work in 10 2/7 days while B and C can complete the same work in 13 1/3 days. If B is 25 percent more efficient than C, in how many days can A and C working together do same work?
⚡More than 1 person⚡
10 men take 15 days to complete a work while 8 women take 25 days to do same work. 10 women started working. They were joined by 3 men after a few days, after which they completed the remaining work together in 5 days. After how many days had the men joined?
⚡Inlet Outlet pipes⚡
1. Two inlet pipes can fill a cistern in 3 hrs and 3hrs 45 min respectively. The outlet pipe can empty it in 1 hr. The two inlet pipes are opened at 1:00pm and 2:00 pm respectively and the outlet pipe is opened at 3:00 pm. At what time would the cistern get empty?
2. There are 8 pipes attached with a tank, some of which are inlet and the rest outlet. An inlet pipe takes 12 hrs to fill the tank completely while an outlet pipe takes 30 hrs to empty it completely. When all the pipes are opened together, the tank get filled in 12 hrs. What is the number of inlet pipes?
3. Pipes A and B can fill a tank in 12 min and 6 min respectively, whereas pipe C can empty it in 5 min. B is opened to fill an empty tank. After sometime, A and C are also opened, after which it takes 15 min to fill the tank. How long was B
a) open
b) open alone
4. Pipes A and B can fill a tank in 15 min and 10 min respectively. When they were opened together, it took 2 min more than what it should take to fill the tank, since there was a leak at the bottom of the tank. What is the which the leak would take to empty full tank?
⚡Variety question⚡
1. Determine which statements are sufficient to answer the question:
Q) In how many days can A and B do the work together?
Statement A: Ratio between efficiency of A and B is 3:1.
Statement B: A and C together can do 1/3 work in 9 days, and B and C can do 2/3 work in 12 days.
Statement C: B can do 2/3 work in 12 days.
Option a) Only A and C
Option b) Only B and C
Option c) C and either B or C
Option d) Data insufficient
Option e) All required
