(B) 12 दिन
(D) 20 दिन
​

Answer 1

Answer:

12 days

Step-by-step explanation:

work can be done by A in 1 day = 1/6

work can be done by A and B together = 1/4

let,

work can be done by B in 1 day =1/x

1/6 +1/x =1/4

1/x = 1/4 - 1/6

1/x = 6-4 / 24

1/x = 2 / 24

1/x = 1/12

x=12

hence B can do work in 12 days.

Answer 2

Answer:

raat me milna kabhi bata denge

how to s3x...besharam

Step-by-step explanation:

AB is the straight line

∠AOQ+∠BOQ=180

o

∠BOQ=180

o

−58

∠BOQ=122

o

In triangle BOQ,OB+OQ are equal since they are radius of the circle (OB=OQ)

So ∠OBQ=∠OQB (Since sides opposite are equal angle opposite to the equal sides are equal)

So ∠OBQ+∠OQB+∠BOQ=180

o

122

o

+2(∠OBQ)=180

o

→∠OBW=29

o

In triangle ABT⇒∠ABT+∠BAT+∠BTA=180

o

=29

o

+90

o

+∠BAT=180

o

∠ATQ=61
