Answer»

Given expression is,

331.80 ÷ 3.80 + 47.80 = 41.17% of 400 - ?

We can WRITE the given values as:

331.80 ≈ 332 and 3.80 ≈ 4

47.80 ≈ 48 and 41.17 ≈ 41

Then,

⇒ 332 ÷ 4 + 48 = 41% of 400 - ?

⇒ 332 ÷ 4 + 48 = (41/100) × 400 - ?

⇒ 83 + 48 = (41 × 4) - ?

⇒ 83 + 48 = 164 - ?

131 = 164 - ?

⇒ ? = 164 - 131

⇒ ? ≈ 33
