Question 3

Which of the following statement(s) is/are TRUE?

I. $$\left(\frac{0.03}{0.2}\right) + \left(\frac{0.003}{0.02}\right) + \left(\frac{0.0003}{0.002}\right) + \left(\frac{0.00003}{0.0002}\right) = 0.6$$

II. $$(0.01) + (0.01)^2 + (0.001)^2 = 0.010101$$

Solution

$$\left(\frac{0.03}{0.2}\right)+\left(\frac{0.003}{0.02}\right)+\left(\frac{0.0003}{0.002}\right)+\left(\frac{0.00003}{0.0002}\right)$$

$$=0.15+0.15+0.15+0.15$$

$$=0.60\ .$$

I is correct .

$$(0.01)+(0.01)^2+(0.001)^2$$

$$=0.01+0.0001+0.000001$$

=0.010101

II is also correct .

D is correct choice.
