43.	Find the breadth whosearea is 17.1cm² & length=2.7greater than itsbreadth?
Answer» ong>Answer: Step-by-step explanation: For example, 8 + 3 + 5 is the same as 3 + 8 + 5 and gives us the same answer, 16. However, when we are performing a subtraction, we need to take extra care with the order of the numbers. Usually with a subtraction, we WRITE the number we are SUBTRACTING from FIRST, and the numbers we are taking away in any order after that. For example, 8 − 5 = 3 This is NOT the same as 5 − 8 = −3 We can see that we have the same numerical answer (3), but that its value is different: 3 in the first calculation, but minus 3 (−3) in the SECOND. Similarly 8 − 5 − 3 = 0, but 5 − 8 − 3 = −6, which is a COMPLETELY different answer. The reason that the answers are different is not because we have put the numbers in the ‘wrong’ order, but because we have not taken care to notice whether they are positive or negative.

Find the CI on Rs. 5000 for 2 years at 5% per annum compounded annually. Also find the SI for Rs. 5000 for 2 years at 5% per annum. Find the difference between both interests.

Answer» ONG>Answer:

1

st

year

Principal, P=RS.5000

Time, T=1 year

Rate of interest ,R=6%

∴simple Interest, SI=

100

PTR

=

100

5000×10×6

=Rs.300

∴Amount=P+SI=Rs.5300

2nd year

Principal = Amount of 1st year=Rs.5300

Rate of interest =8%

Time =1 year

∴ Interest =

100

5300×1×8

=Rs.424

∴ Amount =Rs.(5300+424)=Rs.5724

The interest of 2nd year is the required compound interest. So, C.I=rs.424 and the required amount is Rs.5724
