Question
? = 49.99² ÷ (1.98⁵ + 8.01 × 89.91) + 75.15% of
(263.89 × 49.11) What approximate value will come in place of the question mark (?) in the following question?(Note: You are not expected to calculate the exact value.)Solution
ATQ, ? = 49.99² ÷ (1.98⁵ + 8.01 × 89.91) + 75.15% of (263.89 × 49.11) ? ~ 50² ÷ (2⁵ + 8 × 90) + 75% of (264 × 49) ? ~ 2500 ÷ (32 + 720) + 75% of 12936 ? ~ 2500 ÷ 752 + 9702 ? ~ 3.32 + 9702 ? ~ 9705
