Question
A man rows to a place 24 km distant and comes back in 14
hours. He finds that he can row 4 km with the stream at the same time as 3 km against the stream. The speed of the stream is. type-sscSolution
Let the speed of boat in still water =B and speed of stream =S then Speed of boat in downstream=B+S and distance =4km So now -time =4/B+S Speed of boat upstream =B-S and Distance =3km So, time = 3/B-S ATQ- 
`(sqrt(960.87)xx9.932+sqrt(629.998)xx26.385)/(sqrt(1028.902)xx4.977)=?`
- 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.)
40.02% of 1220.05 = ?2 + 29.09 × 7.99
(1560.23 ÷ 25.98) + (768.32 ÷ 23.9) + 1814.11 = ?
(6.93)2 × (11.98)2 ÷ √361.2 = 7?
(23.99)2 – (17.99)2 + (1378.98 + 44.99) ÷ ? = 608
