Speed upstream = 5 - 2 = 3 km/hr Total distance covered = 14 × 3 = 42 km Speed downstream = 5 + 2 = 7 km/hr Required time = 42/(5 + 2) = 6 hrs
1885 ÷ 64.98 + 7.29 + ? = 69.09
(49 x ?) / 3.5 + 389 = 627
25% of 400 + 3 × 102 = ?2
15% of 2400 + (√ 484 – √ 256) = ?
√10000 x √8100 - (50)² = √(?) + (80)²
13.5% of (100 + ?) = 27
? = (22% of 25% of 60% of 3000) + 21
