1000 litres or 10000 litres

4 x abcd = dcbaa should be 1 or 2a is multiple of 4 so should be even so a = 2d>= 8 but being multiple of 4d = 84bc +3 = cbb is odd or must be 1 or 2 so b = 1Last digit of4bc+3is1, so the last digit of4bcis8andc=2orc=7. Hencec=7abcd = 2178 ans

thanks now I understand the problem

a)1/2,2/4,3/6,4/8 yes all these fractions equivalent

Seg AD=seg BCangle FAD=angle CBE.seg AF =seg BE. ............... property of parallel linesBy SAS test∆ AFD=∆BEC

Given : angle A = 2 angle B

We know in parallelogram the adjacent angles have sum 180°.

A and B are adjacent angles

So,

angle A + angle B = 180°

2B + B = 180°

3B = 180

B = 60°

A = 2 × 60° = 120°

A = C = 120° ( opposite angle of parallelogram)

B = D = 60° ( opposite angle of parallelogram)

6b - 8(4b - 9) + 3b = 6b - 32b + 72 + 3b = 72 - 23b

Expand the bracket, add like terms.

what if we take girls x and boys y answer is coming wrong then,,,,BTW Thanks

Answer:

Step-by-step explanation:

Money spends on a book = (1/8)*300=300/8=37.5

Money spend on her dress= (3*300)/5

=900/5 =180

Total money she spend=180+37.5=217.5

Money left with pooja =

total - spend

=300-217.5= 82.5

pooja left 82.5 rsplz like my answer

Pooja spend total money 1

Pooja= 82.5plz like my answer

she spent on book=300×1/8 =75/2 spent on dress=300×3/5 =180total spent=180+75/2 =(360+75)/2 =435/2=217.5 rs.money left=300-217.5 =82.5 rs. ans.

Please post the question in english!

Let Total number if friends give Rs 200 =x

Then ,

Total number if friends give Rs 300 = 10 -x

From given condition we get

300 ( 10 -x) + 200x = 2700

3000 - 300x + 200x= 2700

- 100x = - 300

x = 3

Therefore,

Total number if friends give Rs 200 = 3

thanks

We will use following trigonometric formulas in this solution -

sin^-1(x) - sin^-1(y) = sin^-1{x√(1-y^2) - y√(1-x^2)}---------(1)

sin^-1(x) = cos^-1{√(1 - x^2)}---------(2)

{We have to prove that,}

sin^-1(3/5) - sin^-1(8/17) = cos^-1(84/85)

LHS = sin^-1(3/5) - sin^-1(8/17)

{Using formula (1) in LHS}

LHS = sin^-1{ 3/5 × √(1 - (8/17)^2 - 8/17 × √1 - (3/5)^2 }

=> LHS = sin^-1{ 3/5 × √(289-64)/17^2 - 8/17 × √8/17 × √(25-9)/25 }

=> LHS = sin^-1{ (3/5 × √(225/289) - 8/17 × √(16/25) }

=> LHS = sin-1 { (3/5 × 15/17) - (8/17 × 4/5) }

=> LHS = sin^-1 (45/85 - 32/85)

=> LHS = sin^-1(13/85)

{By using the formula (2) now}

LHS = cos^-1{√(1 - (13/85)^2)}

=> LHS = cos^-1{√(7225-169)/7225}

=> LHS = cos^-1(√7056/7225)

=> LHS = cos^-1{√(84×84)/(85×85)}

=> LHS = cos^1(84/85) = RHS

{HENCE PROVED}

convert sin in terms of tan we get in the formula tan A-tan B/1+ tanA.tanB

so we can get the solution

Total no. of students in a class = 15 + 10 = 25

Percentage of boys = (15/25)*100

= 60%

Percentage of girls = (10/25)*100

= 40%
