Directions (next six questions) : What should come in place of the question mark(?) in the following questions
(15.5% of 1245) - (12.5% of 1458) = ?
?=[15.5×1245/100]-[12.5×1458/100]
?= 192.975-182.25
?=10.725
?%of 658+40%of 845 = 568.3
1728÷3√262144×?-288=4491
(0.05×6.25)÷2.5=?
968×445÷?=17230.4
The speed of the boat in still water is 24 km/h and the speed of the stream is 4 km/h. The time taken by the boat to travel from A to B downstream is 36 minutes less than the time taken by the same boat to travel from B to C upstream. If the distance between A and B is 4 km more than the distance between B and C, what is the distance between A and B
