Let tap ‘A’ fill the tank and tap ‘B’ empty the tank. Taking LCM of 10 and 15 = 30 Efficiency of A = 3 Efficiency of (A – B) = 2 Efficiency of B = 3 – 2 = 1 Tap B will empty the tank = 30/1 = 30 So, tap B will empty the tank in 30 hours.
Find the approximate value of Question mark(?). No need to find the exact value.
59.88% of 419.78 + (24.09 × 5) ÷ 3 – √(80.81) = ?
...(33.95)2 – (25.004)2 + (18.0099)2 – (9.07)2 = ? - (14.990)2
(√780 + 111.98) ÷ 6.95 + 39.95% of 179.98 = ?
What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.

23.98% of 624.99 = 19.98% of ? + 14.98% of 639.99
29.98% of 549.99 = ? - 254.97 + 79.98% of 74.99
(15.99)2 + 219.98% of 20.01 = ?2 × 75.01%
(32.25 × 14.98) + 31.76% of 1499.89 = ? × 3.67
