64. For what value of "k" will the equation (2kx^2 + 5kx +2)=0 have equal roots?
Answer: 16/25
Explanation:For a 2nd degree equation "ax2+bx-c=0" has equal roots the condition is b2-4ac =0
So in the given equation (2kx^2 + 5kx +2)
a=2k, b=5k, c=2
=> (5k)^2-4(2k)(2)=0
=> 25k^2-16k=0
=>k(25k-16)=0
=> k=16/25;

65. A 5-digit number is formed by the digits 2,4,5,6,8 (each digit used exactly once) . What is the probability that the number formed is divisible by 4 ?
Answer: 2/5
Explanation:A no. is divisible by 4 if last two digit is divisible by 4
so numbers ending with 24,28,48,52,56,64,68,84 are divisible by 4
last two places are fixed by 24,28,48,52,56,64,68,84
so remaining 3 places can be filled in 3! ways for each
total=8*3!=48=n(E)
n(S) = 5!
so
= n(E)/n(S)
=48/120=2/5

67. A man reaches his office 30 min late, if he walks from his home at 3 km per hour and reaches 40 min early if he walks 4 km per hour. How far is his office from his house?
Answer: 14km
Explanation:Lets assume distance between office and his house =x km
Time taken when speed is 3 kmph = x/3 min.
Time taken when speed is 4 kmph = x/4 min.
Difference between time taken 40-(-30) = 70mins = 70/60 hours.
x/3- x/4 = 70/60
x/12= 7/6
x=14 km

68. A sum of Rs 468.75 was lent out at simple interest and at the end of 1 year and 8 months, the total amount of Rs 500 is received. find the rate of interest.
Answer: 4%
Explanation:Given principle P=468.75, Rate of Intreset = R%
Total Amount received = Rs 500
=> Total Amount received = Simple Intrest + Principle.
=> 500 = [468.75*(20/12)*R]/100 + 468.75
=> 31.25=156.25*5R/100
=> R=4%

69. In a certain college, 20% of the boys and 40% of the girls attended the annual college outing. If 35% of all the students are boys, what percent of all the employees went to the outing?
Answer: 33%
Explanation:Lets assume total students =100
so in that 35 students are boys and remaining 65 will be girl.
20% of boys = (35)*20/100 = 7
40% of girls = (65)*40/100 = 26
Totally (26+7)=33 employee went to outing.
So 33 is 33% in 100
=> 33% employees went for outing.

70. Radha bought a watch for Rs. 144 and got a percentage of profit equal to the cost price of the watch. What is the cost price of the watch?
Answer: Rs. 80
Explanation:SP=144
Lets assume cost price of watch= Rs. x
so profit %=x
C.P.= (100/(100+gain%))*S.P. -----(formula to get CP)
x=(100/100+x) *144
=> x^2+100x=14400
=> x^2+180x-80x-14400=0
=> (x+180) (x-80)=0
=> x=-180
=> x=80
