Ques:- There are 6 couples (12 people). 4 people are selected at random. What is the probability that exactly one couple will be selected ?
Recent Answer : Added by An On 2022-09-15 16:37:14:
Prob(choosing two people who are a couple from 6 couples) = 1/6
We have 5 couple left (10 people)
Prob(choosing a person A from 10 people) = 1/10
Prob(choosing 1 person who is not a couple of A) = 1/8
Prob(choosing 4 people that has exactly one couple) = 1/6*1/8*1/10 = 0.0021

Ques:- If A lends Rs.3500 to B at 10% per annum and B lends the same sum to C at 11.5% per annum then the gain of B in a period of 3 years is?
Recent Answer : Added by LYNETTE On 2021-11-09 15:53:46:
3500*10/100
3500*11.5/100 = 402.5 per year
402.5×3 = R1207.5
Ques:- Find the odd man out:
385, 462, 572, 396, 427, 671, 264
A. 671
B. 427
C. 385
D. 264
Recent Answer : Added by Manthan Shukla On 2022-03-11 17:00:08:
427 is the answer
Because
385 means (3+5=8) or (8-3=5) ,
462 means (4+2=6) or (6-2=4) ,
572 means (5+2=7) or (7-5=2) ,
396 means (6+3=9) or (9-3=6) ,
671 means (6+1=7) or (7-6=1) ,
264 means (4+2=6) or (6-2=4) ,
but only 427 is the number in which if we do addition of any of its two digits (e.g 4+2 or 4+7) then its answer doesn’t come 3rd digit
like if we do 4+2 then answer will be 6 so the number should be 426 but it is not
or if we do 7-4 then answer will be 3 (not 2)
so the right answer is 427

Recent Answer : Added by Manik rattan On 2021-08-16 06:56:14:
suppose
pipe:
A -30 hours A’s effeciency (60/30) =2
60( lcm of 30 and 20)
B- 20 hours B’s effeciency (60/20)=3
time taken by both to fill = 60/5 =12 as given in question (effeciencies of both a+b =2+3=5)
time taken by faster pipe i.e b = 60/3 =20
