The selling price of a smartphone is ₹12000. Its cost price was ₹15000. Find the percentage loss in the price of a phone.​

Answer»

Answer:

11,250

Step-by-step explanation:

INTERPRETING terms in the most common way:

The discounted PRICE would be Rs12,000 x 90/100 =RS 10,800.

Rs 10,800 = a LOSS of 4% i.e.96% of cost price = cost price/100x96

therefore cost price = Rs 10,800x100/96x100 = Rs 11,250.

If (x+y)=(a+bi)²,show that (x²+y²)=(a²+b²)²​

Answer»

Answer:

(a+ i.b)^2 = X + i.y.

or, a^2+ i^2.b^2+ i.2AB = x + i.y.

or, a^2 - b^2 + i. 2ab = x + i. y.

or, Comparing the real and imaginary parts both sides.

x = a^2 - b^2. …………(1).

y = 2ab. …………………..(2)

Squaring and adding both sides the eqn. (1) and (2).

x^2 + y^2 = (a^2 - b^2)^2 +(2ab)^2.

or, x^2 - y^2 = a^4+b^4-2a^2.b^2+ 4a^2b^2 = a^4+b^4+2a^2b^2.

or, x^2 - y^2 = (a^2+b^2)^2. Proved.

A+b+c=10,a²+b²+c²=22 हो तो ab+bc+ca का मान क्या होगा​

Answer»

GIVEN :-

a + b + C = 10

a² + b² + c² = 22

Now,

(a + b + c)² = a² + b² + c² + 2(ab + bc + ca)

(10)² = 22 + 2(ab + bc + ca)

100 - 22 = 2(ab + bc + ca)

ab + bc + ca = 39 ANSWER....

Find the amount if principal is 50000 at 12% p.a for 1 ½ year if interest is calculated compoundedhalf yearly​

Answer»

ANSWER:

Step-by-step explanation:

It is given that  

Principal (P) = 50000

Rate of interest (r) = 8% p.a. = 4% semi-annually

Period (n)= 1  

2

1

​  

 years = 3 semi-annually

We KNOW that  

AMOUNT = P(1+r/100)  

n

 

Substituting the values  

= 50000(1+4/100)  

3

 

By further calculation  

= 50000(26/25)  

3

 

= 50000×26/25×26/25×26/25

= 56243.20

Here

Compound interest = A - P

Substituting the values  

= 56243.20−50000

= 6243.20

Q.12 The opposite angles of a parallelogram PQRS are angle Q = (5x-16)° and angle S = (2x+29)°. Find all the angles of parallelogram.​

Answer»

Given:

  • The opposite ANGLES of a Parallelogram is (5x-16)° and (2x+29)°

\\

To FIND:

  • Find all the angles of parallelogram.

\\

Solution:

{\underbrace{\tt\large{ Understanding \ the \ Concept }}} \\

  • The opposite sides of Parallelogram are ALWAYS equal.
  • The corresponding sides of a Parallelogram are supplementary of each other.

So,

The sides are opposite ie equal.

\colon\implies 5x - 16 = 2x + 29

\colon\implies 5x - 2x = 29 + 16

\colon\implies3x = 45

\colon\implies{\tt{ x = \cancel{ \dfrac{45}{3} } }}

\colon\implies x = 15°

So, After substituting values,

\implies 5(15) - 16

\implies 75-16

\implies 59°

So, In this way we can find the Other Angles of the Parallelogram:

180 - 59 = 121°

Hence,

  • 121°, 121°, 59° and 59° are the angles of Parallelogram.

40°+x+50°= 180° ( linear pair)

90° + x= 180°

x= 90°

z= 40° ( vertically OPPOSITE angles)

y + z = 180° ( linear pair )
