Answer:
100 rupee notes= 6, 50 rupee notes=3
Step-by-step explanation:
3 x 50 = 150
6 x 100 = 600
600 + 150 = 750
and 3 x 2 = 6, so the amount of 100 rupee notes are twice the amount of 50 rupee notes.
Hope this helps :)
Answer:
66. Assuming after you substituted 3 in place of x, you followed order of operations, or PEMDAS.
Step-by-step explanation:
6(2x) + 9x +3 = area
6 (2(3)) + 9(3) + 3 = area
6 x 6 + 27 + 3 = area
36 + 30 = 66
area = 66
A bit messy.Pls don't mind it
Solution :
Given :
Principal amount deposited, P = $ 6000
Rate of interest, r = 5%
Number of years, t = 4 years
When the deposited amount is compounded semiannually, i.e. n = 2
Therefore,
Future value,



= 6000 x 1.2184
= 7310.4
Therefore, after 4 years there will be $ 7310.4 in the amount when compounded semi annually.
When the deposited amount is compounded quarterly, i.e. n = 4
Therefore,
Future value,



= 6000 x 1.219889
= 7319.334
Therefore, after 4 years there will be $ 7319.334 in the amount when compounded quarterly.
When the deposited amount is compounded monthly, i.e. n = 12
Therefore,
Future value,



= 6000 x 1.22089
= 7325.34
Therefore, after 4 years there will be $ 7325.34 in the amount when compounded monthly.

Since we need to solve for r we have to leave that variable alone in one side of the equation. We notice that at is adding in the right side, then it goes to the left side substracting, that is:

Therefore:

in the last part we only switch the sides of the equation.
