- A0.12
- B0.012
- C0.36
- ✓0.06
Answer
View full question & answer→Correct option: D.
0.06
GST = CGST + SGST since,(CGST = SGST)
GST = CGST + CGST
12% = 2 CGST
12/2 = CGST
6 = CGST
therefore, CGST = SGST = 6% = 0.06
GST = CGST + CGST
12% = 2 CGST
12/2 = CGST
6 = CGST
therefore, CGST = SGST = 6% = 0.06

If the face value of share is $Rs.100$ when market value was $Rs.90.$ Company declared $20\%$ dividend. The dividend per share is .$...........$
- A$Rs.24$
- ✓$Rs.20$
- C$Rs. 300$
- D$Rs.150$
Answer
View full question & answer→Correct option: B.
$Rs.20$
To calculate the dividend per share, you can use the formula:
$\text{Dividend per share} = \text{Face value} \times \left(\frac{\text{Dividend rate}}{100}\right)$
Given:
Face value $= Rs. 100$
Dividend rate $= 20\%$
Now, substituting the values:
$\text{Dividend per share} = 100 \times \left(\frac{20}{100}\right) = 100 \times 0.2 = Rs. 20$
Therefore, the dividend per share is $Rs. 20.$
$\text{Dividend per share} = \text{Face value} \times \left(\frac{\text{Dividend rate}}{100}\right)$
Given:
Face value $= Rs. 100$
Dividend rate $= 20\%$
Now, substituting the values:
$\text{Dividend per share} = 100 \times \left(\frac{20}{100}\right) = 100 \times 0.2 = Rs. 20$
Therefore, the dividend per share is $Rs. 20.$

The roots of the quadratic equation $x^2+8 x+15=0$ are
$ x^2+5 x+3 x+15=0 \quad \ldots$
$5 \times 3=+15$
$5+3=+8$
