Answer»

Approximating the values to the NEAREST integer:

65.40 ≈ 65, 2.10 ≈ 2 and 64.33 ≈ 64

35.10 ≈ 35, 5.98 ≈ 6

⇒ (65.40 × 2.10) + 64.33% of 900 = 35.10 × ? + 5.98

⇒ (65 × 2) + 64% of 900 = 35 × ? + 6

⇒ 130 + (64/100) × 900 = 35 × ? + 6

⇒ 130 + 64 × 9 = 35 × ? + 6

⇒ 130 + 576 = 35 × ? + 6

706 = 35 × ? + 6

⇒ ? × 35 = 700

⇒ ? ≈ 20
