If two dice are thrown together, the probability of getting an even number on one die and an odd number on the other is? | [
"7/9",
"1/8",
"1/2",
"1/6"
] | C | The number of exhaustive outcomes is 36.
Let E be the event of getting an even number on one die and an odd number on the other. Let the event of getting either both even or both odd then = 18/36 = 1/2
P(E) = 1 - 1/2
= 1/2.

Excluding stoppages, the speed of a bus is 65 kmph and including stoppages, it is 48 kmph. For how many minutes does the bus stop per hour? | [
"15.6 min",
"20.4 min",
"15 min",
"40 min"
] | A | D
15.6 min
Due to stoppages, it covers 17 km less.
Time taken to cover 17 km = (17/65 x 60) min = 15.6 min | AquaRat_train |

The S.I. on a certain sum of money for 3 years at 8% per annum is half the C.I. on Rs. 4000 for 2 years at 10% per annum. The sum placed on S.I. is? | [
"Rs. 1750",
"Rs. 1550",
"Rs. 2500",
"Rs. 2000"
] | A | Explanation:
C.I. = [4000 * (1 + 10/100)2 - 4000]
= (4000 * 11/10 * 11/10 - 4000) = Rs. 840.
Sum = (420 * 100)/(3 * 8) = Rs. 1750

n a 1000m race, if A gives B a start of 40m, A wing by 19sec. But if A gives B start of 30sec, B wins by 40m.
Find the time taken by B to run 3000m race? | [
"375",
"350",
"425",
"400"
] | A | then 960/B -1000/A = 19 => 24/B - 25/A = 19/40

solving equation A speed =8 and B=20/3
for 1000m b will take 3000/20/3= 375 sec
