why did you subtract 8?

for the case when interest is compounded annually. The question is mentioning the excess or deficit of the interest.

Nice solution bhai but I couldn't get this part -
50 m no. of crossings + meeting = (650-50)/50 = 12 (-50 bcoz , in first round they wont meet or cross)
I couldn't get this logic. why are you assuming that they will meet in every 50 meters ? please explain this sir
50 m no. of crossings + meeting = (650-50)/50 = 12 (-50 bcoz , in first round they wont meet or cross)

looking from faster person perspective , in the first roundtrip(first 50m) they wont meet each other.
only when the faster person returns for second 50m , they will meet for the first time. so deducted 50.
they will meet every 50 m once..had speed of one been twice(or more than twice) of other , there was a chance of faster person crossing slower one twice in one roundtrip
Average age of 38 students is 14 years. If the age of the teacher is included, the average becomes 14 years and 4 months. Then Teacher's age is ???

14 + 39*4/12 = 27

Age of teacher = 27 years.
Which is the better book between Arun Sharma and Quantum Cat for QA ?

(38*14 + x)/39 = 14 1/3 (14.33)
532 + x = 14.33*39
x = 26.87 ~ 27

Wrong thread. 
. My take will be Quantum CAT. ask it in Prep resources thread.

if p^q is a perfect square and perfect cube it can be represented atleast two ways in the form of p^q . then how will we know what is q?
answer should be e) CBD
