Hours (h) Cotton (kg) Days

3. 2. 12

4. 10. (?)

= 4×10×12

--------------

3×2

= 4×10×2

= 80 days

Answer 2

Answer:

45 days

Step-by-step explanation:

In 12 days she spun 2 kg cotton balls,

Applying unitary method.

Daily, she spun 2/12 kg cotron balls.

As it is given she works 3 hours a day,

For 3 hour work, she spun 2/12 = 1/6 kg ball,

For 1 hour work, she spun 1/6×3 = 1/18 kg ball,

For 4 hour work, she spun 4/18 kg ball.

Since, as calculated

she spins 4/18kg ball daily.

So, days taken by her to spin 10kg ball = 10/4/18

= 18×10/4 = 45 days
