A boat’s speed in still water is 10 kmph while river is flowing with a speed of 6 kmph and time taken to cover a certain distance upstream is 6 hours more than time taken to cover the same distance downstream. Find the distance that is travelled by the boat?

Correct

Explanation :
Speed of Still water = 10 kmph
Speed of stream = 6 kmph
Downstream Speed = 16 kmph
Upstream Speed = 4 kmph
Distance = x
x/4 – x/16 = 6
3x = 96 → x = 32

Incorrect

Explanation :
Speed of Still water = 10 kmph
Speed of stream = 6 kmph
Downstream Speed = 16 kmph
Upstream Speed = 4 kmph
Distance = x
x/4 – x/16 = 6
3x = 96 → x = 32

The ratio of the number of boys and girls in a college is 11:9. If 20% of the boys and 10% of the girls are scholarship holders, the percentage of the students who are not scholarship holders is?

Correct

Explanation:
Consider Total no of students = 100
Ratio is 11:9 i.e Boys=55 and Girls=45
20% of boys who get scholarship = 55*20/100=11%
10% of girls who get scholarship = 45*10/100 =4.5%
Therefore % of students who do not get scholarship =100-(11+4.5%) = 84.5%

Incorrect

Explanation:
Consider Total no of students = 100
Ratio is 11:9 i.e Boys=55 and Girls=45
20% of boys who get scholarship = 55*20/100=11%
10% of girls who get scholarship = 45*10/100 =4.5%
Therefore % of students who do not get scholarship =100-(11+4.5%) = 84.5%
