5% interest compounded annually for 3 years multiplies the initial balance by
... 1.05^3 = 1.157625
5% simple interest for 3 years multiplies the initial balance by 1 + 3*0.05 = 1.15.
The difference of these multipliers is
... 1.157625 - 1.15 = 0.007625
If the difference in account balance is Rs 61.00, then the invested principal amount P is
... P*0.007625 = 61.00
,.. P = 61.00/0.007625 = 8000.00
The sum of money is Rs 8000.
Answer:
3 5 -5 2 and 7 are the numbers
To find the minimum, take the derivative of the function and equate to zero:
f(x) = y = x² + ax + b
dy/dx = 2x + a = 0
Substitute x =6:
a = -2x
a = -2(6)
a = -12
Then, substitute x = 6, y = 7 and a = -12 to find b.
7 = (6)² -12(6) + b
7 + 36 = b
b = 43
Thus, a = -12 and b = 43
