It takes 1.5 hours for 4 workers to paint the same room
<em><u>Solution:</u></em>
Given that 3 workers can paint a room in 2 hours
To find: Time taken for 4 workers to paint the same room
Assume the time needed to paint the room is inversely proportional to the number of worker

Where, "k" is the constant of proportionality
<em><u>3 workers can paint a room in 2 hours</u></em>
Substitute number of workers = 3 and time = 2 hours

Therefore,

To find time taken for 4 workers to paint the same room, substitute number of workers = 4 in above expression

Thus it takes 1.5 hours for 4 workers to paint the same room
Answer:
Sum of the opposite pair of a cyclic quadrilateral is 180°.
c= 180-102= 78°
c= 180-102= 78°d= 180-92= 88°
<em><u>intercepted arc</u></em>
=>2(102°)= 140+a°
a=64°
<u>Simillarly</u>
=> 2(d°)= a°+b°
b°= 112°
so ....
<u>a=64°</u>
<u>a=64°b=112°</u>
<u>a=64°b=112°c=78°</u>
<u>a=64°b=112°c=78°d=88</u>
