Answer: 4) 540RsExplanation:

Price of 1kg of wheat = Rs.20So, Price of 9kg of wheat = 20*9 =180. rice.

Given,Price of 4 kg of rice = price of 9kg of wheat =Rs.180

Price of 8Kg of rice = 2*Price of 4 kg of rice => 180*2 =360.

Price of 8Kg of rice =360 andPrice of 9Kg of wheat=180

Adding,

Rs.180+Rs.360we get,Rs.540.

first add all the kg weightshence2+5+4+10kg=21kgnow adding all the gram weights500+200+700=1300gmnow 1000gm=1kgso 1300gm=1kg and 300gmadd in 21kghence22kg and 300gm is the weight of total items

Speed=Distance/TimeSb=10/tSc=25/t

Sb/Sc=10/25=2/5

Sb=d/tSc=1000/t

Sb/Sc=d/1000

Therefore, 2/5=d/1000d=400

Option 1 is correct

if p=ab² and q=a²b

LCM of p and q= ab

1/4 is the answer of this wuestion😊

4 kg / 16 kg = (4×1)/(4×4) = 1/4therefore the ratio is 1:4

10kg50gm=10000+50=10050gmhence 15 balls weigh this hence 1 ball will weigh =10050/15=670gmhence for 4kg690gm=4000+690=4690gm4690/670=7balls

thank you sir very much from bottom of mine heart 💜❤

ABCD is cyclic quadrilateral and in cyclic quadrilateral sum of opposite angles is 180.

Therefore,x + 130 = 180x = 180 - 130 = 50°

y + 120 = 180y = 180 - 120 = 60°

z=x+iy in w gives w=[(1+y)-ix]/[(x-1)+iy]

on solving gives: w=[(1+y)-ix]*[(x-1)+iy] / [(x-1)^2+y^2]

= {(x-y-1) -i(x(x-1)+y(y+1))} / [(x-1)^2+y^2]

as |w|=1 , so {(x-y-1)^2+ (x(x-1)+y(y+1))^2} = [(x-1)^2+y^2]^2

on solving the above equation, we have

2x^3+2y^3+2xy(x+y)-2x^2-2xy+2(x+y) = 0

which is (x+y).(x^2+y^2-2x+2) =0 is the locus of Z

Red line is x + y = 7Blue line is x - y = 3

Point of intersection is (5, 2) so solution isx = 5 and y = 2
