View Explanation Hide Explanation Video Solution

Solution

Ten percent of twenty = $$\dfrac{10}{100} \times 20 = \dfrac{200}{100}$$

Twenty percent of ten = $$\dfrac{20}{100} \times 10 = \dfrac{200}{100}$$

$$\therefore$$ sum = $$ \dfrac{200}{100} +  \dfrac{200}{100}$$ = $$\dfrac{2}{100} \times 200$$ 

This is equal to $$2\%$$ of $$200$$

Hence, option D is the correct choice.

View Explanation Hide Explanation Video Solution

Solution

$$112 \times 5^4 = (100 + 10 + 2) \times 625$$ 

$$\Rightarrow$$ $$62500 + 6250 + 1250 = 70000$$

Alternative Explanation:

$$112 \times 5^4 = 16 \times 7 \times 5^4$$

$$\Rightarrow$$ $$2^4 \times 5^4 \times 7$$

$$\Rightarrow$$ $$ 10^4 \times 7 = 70000$$

Hence, option A is the correct choice
