Hich correctly explains how to estimate 33 percent of 87?

Round 33 percent to 20 percent and 87 to 80. Think of 20 percent as 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 30 percent of 80 is 8 + 8, which is 16.
Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 35 percent and 87 to 90. Think of 35 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 35 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 40 percent and 87 to 80. Think of 40 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 40 percent of 90 is 8 + 8 + 8, which is 24.
