Find the difference between s I and C.I on 6000 at 8.% p.a on 2 years​

Answer»

HELLO Frnd

Given as

PRINCIPAL = 32000

Rate = 12%

Time = 3 yrs

SIMPLE INTEREST

as we know

SiMple interest = P × R × T

= 32000 × 12/100 × 3

= 11520

Now Compound Interest

As we know

Compound Interest = AMOUNT - Principal

= 44928 - 32000

= 12928

Now DIFFERECE between Compound Interest and Simple Interest

Difference = C I - S I

= 12928 - 11520

= ₹ 1408

The perimeters of two squares are 40 and 96 metres respectively. Find the perimeter of another square equal in area to the sum of the first two squares

Answer»

Answer:

Step-by-step explanation:

Let the side of two squares be 'a' and 'b'.

Then,

The perimeter of the first square = 4a

Given,

perimeter of first square = 40

According to the QUESTION,

=> 4a = 40

=> a = 40÷4

=> a = 10

Similarly,

perimeter of SECOND square = 4B

Given,

perimeter of second square = 96

According to the question,

=> 4b = 96

=> b = 96÷4

=> b = 24

Let, X be the side of ANOTHER square.

Then,

area of another square = x²

Area of another square = sum of the areas of first and second squares

= (a)² + (b)²

=> x² = (10)² + (24)²

=> x² = 100 + 576

=> x² = 676

=> x =

=> x = 26

Perimeter of another square = 4x = 4*26 = 104m

So,

the perimeter of another square is 104m.

A number is divided into two parts such that one part is 15 less than the other. if the two parts are in the 4:5 , find the number and the two parts.​

Answer»

Answer:

135 = 60 + 75

Step-by-step explanation:

Let ONE part be X then other part is x+15.

The two NUMBERS are in the ratio of 4:5.

\frac{x}{x + 15} = \frac{4}{5}

5x = 4(x + 15)

5x = 4x + 60

5x - 4x = 60

x = 60

One part is 60 then other part is 75.

Number = 60 + 75 = 135.

If a=1/3-2√2 and b=1/3+2√2 evaluate a²b+ab²​

Answer»

If a = 1/[3–2*2^0.5] and B = 1/[3+2*2^0.5], what is the VALUE of a^2b + AB^2?

a^2b + ab^2 = ab(a+b).

ab = 1/[3–2*2^0.5]*1/[3+2*2^0.5] = 1/(9–8) = 1/1 = 1

a+b = 1/[3–2*2^0.5] + 1/[3+2*2^0.5] = [3+2*2^0.5 +3–2*2^0.5]/1 = 6.

Hence, a^2b + ab^2 = ab(a+b) = 6.

Check: a = 5.828427125, b = 0.171572875.

a^2b + ab^2 = 5.828427125^2*0.171572875 + 5.828427125*0.171572875^2

= 5.828427125 + 0.171572875 = 6. Correct.

If A=π\3 and B=π/6 then prove that Tan (A-B) = TanA-TanB/1-TanATanB​

Answer»

Step-by-step EXPLANATION:

TAN (A+B) = [tan A + tan B]/[1 - tan A tan B]

RHS = [tan A + tan B]/[1 - tan A tan B]

=[(sin A/cos A) + (sin B/cos B)]/[1-(sin A/cos A)(sin B/cos B)

= [sin A cos B + cos A sin B]/[cos A cos B][1 - sin A sin B/(cos A cos B)]

= sin (A+B)/{[cos A cos B][cos A cos B - sin A sin B]/(cos A cos B)}

= sin (A+B)/[cos A cos B - sin A sin B

= sin (A+B)/cos (A+B)

= tan (A+B) = LHS.
