Answer:

The correct answer:

1. 100 × 35/100 ⇒ 35% of 100 (2nd and 7th)

2. 200 × 25/100 ⇒ 25% of 200 (4th and sixth)

Explanation:

As it is given that and we know that 25% of 200 can be calculated by multiplying the principle value which is 200 to percentage value divided by 100 (100 is whole value).

Similarly, we can found the calculative representation of 25% of 200 and 35% of 100 are only two values that can be put in boxes after the arrow that are:

1. 100 × 35/100 ⇒ 35% of 100

2. 200 × 25/100 ⇒ 25% of 200
