Number of passed only in 1st = 60-30 = 30
Number of passed only in 2nd = 50-30 = 20
Total passed atleast in one exam = 30 + 20 + 30 = 80
Total failed in both = 100 - 80 = 20
Therefore required probability = 20/100 = 1/5

Two friends decide to get together; so they start riding bikes towards each other. They plan to meet halfway. Each is riding at 6 MPH. They live 36 miles apart. One of them has a pet carrier pigeon and it starts flying the instant the friends start traveling. The pigeon flies back and forth at 18 MPH between the 2 friends until the friends meet.
How many miles does the pigeon travel

Like? Yes | No (1)

(6 Months ago)

Ans: 54 miles

Let two friends are A and B, who lives 36 miles apart.
Case-I (Pigeon first flies from B towards A)
Relative speed of Pigeon and A = 18+6 = 24 mph. Time of meeting Pigeon and A=36/24=3/2 hr.
In time 3/2 hrs, distance traveled by A & B=2*6*3/2=18 miles, Remaining distance=36-18=18 miles.
Case-II (Pigeon then flies from A towards B)
Relative speed of Pigeon and B = 18+6 = 24 mph. Time of meeting Pigeon and B=18/24=3/4 hr.
In time 3/4 hrs, distance traveled by A & B=2*6*3/4=9 miles, Remaining distance=18-9=9 miles.
Case-III (Pigeon first flies from B towards A)
Relative speed of Pigeon and A = 18+6 = 24 mph. Time of meeting Pigeon and A=9/24=3/8 hr.
In time 3/8 hrs, distance traveled by A & B=2*6*3/8=9/2 miles, Remaining distance=9 - 9/2=9/2 miles.
Case-IV (Pigeon then flies from A towards B)
Relative speed of Pigeon and B = 18+6 = 24 mph. Time of meeting Pigeon and B=(9/2)/24=3/16 hr.
In time 3/16 hrs, distance traveled by A & B=2*6*3/16=9/4 miles, Remaining distance=(9/2)-(9/4)=9/4 miles.

Thus Pigeon we fly between A and B, for 3/2, 3/4, 3/8, 3/16, ..... hrs (which forms series) until both the friends meets. Therefore total distance traveled by Pigeon=18*(3/2 + 3/4 + 3/8 + 3/16 + ......)=18*3*(~1)=54 miles.

Let initial salary of each employee be 1.

Then, quantity of remaining milk after removing 24 liters of mixture=7x - 24*(7/8)=56
56x - 168 = 448
x = 11

A person sold an article for 1840 Rs. And profit incurred will be 12.5% more than the loss incurred when article is sold for 1500 rs. At what price it should be sell to get 20% profit?

Reply Like? Yes | No

(10 Months ago)

Ans: Rs. 1992

Let CP=Rs. x, then Profit when SP is 1840 = (112.5/100)*Loss when SP is 1500
(1840-x) = (112.5/100)*(x-1500)
184000 - 100x = 112.5x - 168750
Solving, we get x = 1660
So, SP when profit is 20% = 1660*(120/100) = 1992 Rs.

S43=43(2a+42d)/2[through formulaSn=n{2a+(n-1)d}/2]
So S43=43(2a+42d)/2=2967
Now T11=a+10d
T33=a+32d
T11+T33=2a+42d=2967*2/43
=138

Like? Yes | No

(1 year ago)

Ans: 138

For A.P. series, here n=43, S=2967. If First term=a, Difference=d, then sum of an A.P. series S=(n/2)[2a + (n-1)d]
2967 = (43/2)(2a + 42d)
69 = a + 21d ---- (i)
Sum of 11th term and 33rd term = (a + 10d) + (a + 32d) = 2a + 42d = 2 x (a + 21d) = 2 x 69 = 138
