Direction : (8-10)

The sale of four different products in two different years of a electronics firm is given below in the following table chart.   Study the chart and answer the following questions. 8) The Seller gets a profit of 25% on TV and the ratio of Selling Price of TV in 2012 and 2013 is 5:7. If the Cost price of TV in 2012 is 20000 find the selling Price of TV in 2013

a) 35000

b) 20000

c) 25000

d) 30000

9) What is the sum of TV and Fridge sold in 2012 and Washing Machine and Fridge sold in the year 2013?

a) 253

b) 421

c) 323

d) 289

10) What is the ratio of 75% of AC sold in 2012 to 180% of Fridge sold in 2013?

a) 1:1

b) 2:1

c) 1:2

d) 1:3

(x – 5)2 + (y -1)2 + (z +3)2 = 0

If ( x-a)n=0 , it is clear that x=-a

(x – 5)2 + (y -1)2 + (z +3)2 = 0

X=5,y=1, z=-3

2x + y + z – 2=2(5)+1+(-3)-2=6

tan(90-x)=cot x

Sin(90-x)=cos x

Sin x. cosx =1

Tanx .cot x=1

tan 32° sin 26° cos 45° sin 64° tan 58°

=tan 32° sin 26° cos 45° sin (90-26°) tan (90-32°)

= tan 32°tan (90-32°)sin 26°sin (90-26°)cos 45°

= tan 32° cot 32°sin 26°cos 26ocos 45°

=1.1. cos 45°

= cos 45°

=1/√2

Divisibility rule of 8 is last three digits of the number should be divisible by 8.

If n=2 , the number is 2224. It is divisible by 8

If n=6 , the number is 2664. It is divisible by 8

Diameter of Sphere= 18.2

T.S.A of Sphere= 4πr2

T.S.A of sphere =4×22/7×9.1×9.1=1041.04

T.S.A of Hemisphere= 3πr2

T.S.A of 2 hemisphere=2(3×22/7×9.1×9.1)=780.78

1041.04-780.78=260.26 cm2

Hence,the correct answer is 260.26 cm2

Let the marked Price and cost price be x and y respectively.

4.17%=1/24

9.09%=1/11

Selling Price = Marked Price- Discount= x-x/24=23x/24

10327——–23

x————–24

x=24×10327/23=10776

Marked Price= 10776

Without any discount Selling Price = Marked Price=10776

Cost Price= Marked Price –Profit

y+(y/11)= 10776

12y/11=10776

y=9878 Average of 15 results= 120

Sum of 15 results=120×15=1800

Average of first 8 results= 130

Sum of first 8 results=130×8=1040

Average of last 8 results= 142

Sum of last 8 results=142×8=1136

Eighth result =1040+1136-1800=376

25% of 8th result= 1/4×376=94

Direction (8-10) :

Cost Price of TV in 2012

Selling Price of Tv in 2012= 125/100 x20000= 25000

Selling Price of Tv in 2012: Selling Price of Tv in 2013 =5: 7

5——25000

7——-?

?= 7×25000/5

?=35000

Selling Price of Tv in 2013= 35000

TV and Fridge sold in 2012= 53+40= 93

Washing Machine and Fridge sold in the year 2013=50+180=230

Sum= 230+ 93=323

AC sold in 2012=120

75% of AC sold in 2012=75/100×120=90

Fridge sold in 2013=50

180% of Fridge sold in 2013= 180/100× 50= 90

Ratio= 90: 90

=1:1
