A boatman can row 96 km downstream in 8 hr. If the speed of the current is 4 km/hr, then find in what time he will be able to cover 8 km upstream ? | [
"1 hrs",
"1.5 hrs",
"2 hrs",
"2.5 hrs"
] | C | Explanation:
Speed in downstream = 96/8 = 12 kmph
Speed of current = 4 km/hr
Speed of the boatman in still water = 12 – 4 = 8 kmph
Speed in upstream = 8 – 4 = 4 kmph
Time taken to cover 8 km upstream = 8/4 = 2 hours.

"5",
"12",
"13",

Kishore has 4 pairs of shoes; each pair is a different color. If Kim randomly selects 2 shoes without replacement from the 8 shoes, what is the probability that she will select 2 shoes of the same color? | [
"1/9",
"1/7",
"1/25",
"1/5"
] | B | Can be tackled in this way as well: Probability of selecting any 1 out of 8 shoes = 8/8 = 1
Probability of selecting the next shoe (out of 8 available) having the same color = 1/7 (as after selecting the 1st one, there is only 1 another shoe left with the same color).
Thus the total probability = 1*1/7=1/7.
