Pls check the qn.

After every hour a number increases 15 % of its present value. How many times it will increase in 8 hours.

Pls check that new value will become 3 times the original value after 8 hours but the no of times , its value is increased is 2 times.
The qn is about increase in value and not about final value.
so answer should be 2 times and not 3 times.

actual answer we will get is

as per general mathematics, 15.555555... rounded to 1 digit will be 15.6(as this is not in options) on further rounding of we get 16.

@ Kalpana,
A person goes to office either by car, jeep, bus or train. The probabilities of which being 2/7, 3/7, 1/7 ,1/7 respectively. The probability that he reaches office later if he takes jeep, bus, car or train is 2/9, 1/9, 5/9, 2/9 respectively.

pls note that here sum of prob. of using car, jeep, bus or train is 1.The probability that he reaches office later if he takes jeep, bus, car or train is 2/9, 1/9, 5/9, 2/9 respectively.
The probability that he reaches office in time if he takes jeep, bus, car or train is 7/9, 8/9, 4/9, 7/9 respectively. These prob have no relation with other mode . But sum of prob of reaching late or not using a particular mode is 1.

I can't understand the explanation for 28 Apr,2o11 Question. The Question Was "A person goes to office either by car, jeep, bus or train. The probabilities of which being 2/7, 3/7, 1/7 ,1/7 respectively. The probability that he reaches office later if he takes jeep, bus, car or train is 2/9, 1/9, 5/9, 2/9 respectively. If he reaches office in time, then the probability that he travelled by car is" but answer explanation was " the probability that he travelled by car is 2/7
The probability that he reaches office later if he takes car is 5/9
So probability that he reaches office in time by car =(2/7)*(4/9)= 8/63
Similarly probability for jeep = (3/7)*(7/9) = 21/63
Similarly probability for bus = (1/7)*(8/9) = 8/63
Similarly probability for train = (1/7)*(7/9) = 7/63
so required probability = (8/63)/(8/63)+(21/63)+(8/63)+(7/63)= 8/44 = 2/11" First how comes "(8/63)/(8/63)+(21/63)+(8/63)+(7/63)=8/44" ?

i would like to request for changing the timing of daily question.please shift it to 8 a.m. instead of 11 a.m. because in most schools and college's timing are not relevant to this.Generaly we go their colleges at 9 a.m. and come till 2p.m. thats why we always becomes late in giving the answers at 11 a.m. whisch are not feasible for us.
so please try to understand our problems and change the timing..
