Question
A man can row at 3 kmph in still water. If the velocity
of current is 2 kmph and it takes him 6 hour to row to a place and come back, how far is the place?Solution
Let the distance be x km. Speed upstream = 3 – 2 = 1 kmph Speed downstream = 3 + 2 = 5 kmph => (x/5) + (x/1) = 6 => (x + 5x)/5 = 6 => 6x = 30 => x = 5 km

Solve the following expression and calculate the approximate value.
398% of 388 + 129% of 323.89 – 430.93
30.11% of 149.99 + √ 143.97 ÷ 12.02 = ?
(74.76 ÷ 12.11 X ?)% of 239.89 = 600.19
