Answer:
Let us consider that ,
The worker can complete the work in x hours .
So, he can complete 1/x part of work in 1 hour.
Now, The workers does 2/3 of what he does. So they do 2/3(1/x) part of work in 1 hour . 2/3x work in 1 hour .
Consider them all working together,
So work done in one hour, = 1/x + 2/3x + 2/3x = 3 + 4 / 3x = 7/3x .
So, They taken 1 hour to complete 7/3th part of work. So, In 3x/7 hours , They all can complete the work.
Ratio of the time taken by all instead of only one = 3x/7 : x = 3/7 .
So ,The required option is 3/7

Answer:
30°
Step-by-step explanation:
<u>Angles and Quadrants:</u>
- 0° to 90° -- Quadrant 1
- 90° to 180° -- Quadrant 2
- 180° to 270° -- Quadrant 3
- 270° to 360° -- Quadrant 4
<u>Formula for Reference Angle in each Quadrant:</u>
<em> is the angle given</em>
- Quadrant 1 -- Reference Angle =
- Quadrant 2 -- Reference Angle =
- Quadrant 3 -- Reference Angle =
- Quadrant 4 -- Refence Angle =
Angle given is 150°, which according to first table, falls in Quadrant 2.
According to second table, the reference angle is found by subtracting 150° from 180°.
Reference Angle = 180° - 150° = 30°
