Concept:Approximate the given numbers to nearest whole numbers or easy perfect squares to simplify the arithmetic. Then evaluate the expression step by step.Explanation:Round each value to a nearby whole number: 169.89 ≈ 170, 101.96 ≈ 102, 16.93 ≈ 17, 33.98 ≈ 34, 198.11 ≈ 198, 120.87 ≈ 121, 32.89 ≈ 33, and √35.97 ≈ √36 = 6.Now rewrite the expression: (170 × 102) ÷ (17 × 34) + (198 × 121) ÷ (33 × 6).First term: 17170=10, 34102=3. So 10×3=30.Second term: 33198=6, then 6×6121=121. So second term = 121.Add both: 30+121=151.Answer:The approximate value is 151, which matches option B.
