Total distance = 300 km + 200 km = 500 km Total time = 300 km / 60 km/h + 200 km / 80 km/h = 5 hours + 2.5 hours = 7.5 hours Average speed = Total distance / Total time = 500 km / 7.5 hours = 66.67 km/h or 68 km/h (approximately)
? = 650.24 + 1124.97 – 14.992
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.)...

(2099.92 ÷ 25.02 of ? × 199.56 + 1199.95) = 3999.86
(11.98% of 449.99) - 3.998 = √?
63.89% of 549.68 – (739.87 ÷ 5.34) = ? × 11.89
20.11% of 119.99 + √80.97 ÷ 3.02 = ?
7.898 × ? + 139.89` ` `-:` 14.23= 4004.04 – 353.89
