Question
If a project needs an initial investment of 25,000,
calculate the payback period from the below given informationSolution
It is evident form the above table that in 3 years 22,000 has been recovered and 3,000 is left of initial investment of 25,000. It indicates that payback period is between 3 to 4 years calculated as follows: Payback period = 3 years + 3000/6000 = 3.5 years.
The HCF of any set of 10 co-prime numbers is always:
Let N be the greatest number that will divide 86, 120, 154 leaving the same remainder in each case. Then sum of the digits in N is:
- The least common multiple (LCM) of two numbers is 144, and the numbers are in the ratio 4:6. Find their sum.
- The sum and the difference of the L.C.M and H.C.F of two numbers are 486 and 342. If one of the numbers is 18, find the other number.
