Answer»

We can write following VALUES as :

97.66 ≈ 98, 3.94 ≈ 4 and 4.14 ≈ 4

2.90 ≈ 3, 44.80 ≈ 45 and 185.91 ≈ 186 and 3.01 ≈ 3

Given expression is,

⇒ (97.66 × 3.94 + 4.14) ÷ 2.90 + 44.80 = 185.91 + 3.01 × ?

⇒ (98 × 4 + 4) ÷ 3 + 45 = 186 + 3 × ?

⇒ (392 + 4) ÷ 3 + 45 = 186 + 3 × ?

⇒ 396 ÷ 3+ 45 = 186 + 3 × ?

⇒ 132 + 45 = 186 + 3 × ?

⇒ 177 = 186 + 3 × ?

⇒ ? × 3 = 177 - 186

⇒ ? ≈ -9/3 ≈ -3
