if u assume x and y and solving u will be annoyed.

Provided 1/4 is the saving, 3/4 is the expenditure

so Expenditure=3, Income = 4

first make A’s Income and Expenditure ratio parts as below

A

7*8 9*7 12*7

8*7 9*7 15*7

Now make first one as 4 parts by multiplying 4 and second make 3 parts by multiplying 3

A’s Income = 7*8*4 = 224

A’s Expenditure = 8*7*3=168 Saving = 56

Now

B’s Income = 9*8*4 = 288

B’s Expenditure = 9*7*3=189 Saving = 99

A’s Income = 12*8*4 = 384

B’s Expenditure = 15*7*3=315 so Saving = 69

Ratio 56:99:69.

[In the last step, the L.C.M. of the denominators of each term is multiplied to each term of the ratio. And then each term is divided by the H.C.F. of numerators of each term of the ratio.]

Therefore the ratio of savings(A:B:C)=56:99:69 .

Area of circle=πr^2308=(22/7)r^214*7=r^2r^2=98r=7√2cm

Perimeter of semi circle=πr+2r=(22/7)*7√2+2(7√2)=22√2+14√2=36√2cmoption 4 is correct

we know that arthimetic mean A=a+b/2.now,(A-a)²+(A-b)²=(a+b/2-a)²+(a+b/2-b)²=(a+b-2a/2)²+(a+b-2b/2)²=(b-a/2)²+(a-b/2)²=(b²+a²-2ab+a²+b²+2ab)/4=2(a²+b²)/4=(a²+b²)/2 is the answer.

Let the number of bees = xThen the number of flowes = (x - 1)If the number of bees sitting on each flower is 2, number of flowers is (x/2 + 1).⇒ (x/2 + 1) = (x - 1)⇒ x - x/2 = 2⇒ x/2 = 2⇒ x = 4Therefore, number of bees is 4 and the number of flowers is (4 - 1) i.e. 3.

To find this add all the number of flowershence72+57+25=154 flowers

72+57+25=154 flowers

Orchids -72. Roses-57.Lilies-25. add all 72+57+25=154 Flowers

It was sold at a loss of 2,350. So the Selling price = Cost price- Loss=19450-2350 =17100 rs

thanks sire

Iftheanglebetween theincident rayandreflected rayis90°, theangleofreflectionis half of90° i.e., 45° . Always, theangle of incidence= theangleofreflection. This means that theanglewhich the normal makes with theincident rayis the same as theanglewhich the normal makes with thereflected ray.

5/6 * 100= 83.333 %

5/6 * 100=83.333So 100-83.333=16.666

a)25b)one dozen means 12 and 12÷4 is 3

1/2 × 50 = =50/2 = 25

1/2*50=50/2=25the answer is right

(a) 1/2*50=25(b) 1/4*12=3is the correct answer

% reduction = [(500-425)/500] * 100 = (75/500) * 100 = (0.15)*100 = 15%

Thank you so much

Selling price = 4000loss = 20%cost price=?=100/(100-20)*4000100/80*40005000 rupees

x + 5x/100 = 2058

105x = 205800

x = 1960 rupees

Discount= ₹3S.P.= 42so,real cost of the article on which discount of ₹3 is given=42+3= 45so percentage of discount = 3/45 * 100 = 20/3=6.66%

redusction % = (400-500)/500 = -100/500 = -20%

answer is negative because it is a loss

at the back ans. is rupees 2000 and rupees 30...

cosecx=1/sinxand secx=1/cosxhencesin^2(90-x)+cos^2(90-x)=1 hence proved

Cosθsinθ - sinθcos(90°-θ)cosθ/sec(90°-θ) - cosθsin(90°-θ)sinθ/cosec(90°-θ) +cosec(90°-θ)

=cosθsinθ - sinθsinθcosθ/cosecθ - cosθcosθsinθ/secθ - secθ

=cosθsinθ - sin³θcosθ- cos³θsinθ- secθ

=cosθsinθ(1-sin²θ - cos²θ) - secθ

=cosθsinθ(1-1) - secθ

=0 - secθ

=1/cosθ

discovery of bulb by thomas Edison

Edison was inventor of bulb.

The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light. He was neither the first nor the only person trying to invent an incandescent light bulb
