Explain me in step by step :

Shatabdi Express has a capacity of 500 seats of which 10% are in the Executive class and the rest are chairs. During one journey, the train was booked to 85% of its capacity. If executive class was booked to 96% of its capacity, then how many chairs were empty during that journey

Answered by kvnmurty

total seats = 500
executive class = 10% of 500 = 500 * 10/100 = 50
number of chairs = 500 - 50 = 450
total number of booked/reserved seats = 85% of 500 total seats = 425
number of executive class seats booked = 96% of total executive class seats
= 96/100 * 50 = 48
Total seats booked = executive seats booked + chairs booked
so 425 = 48 + chairs booked
chairs booked = 377
chairs empty = total number of chairs - chairs booked = 450 - 377 = 73

nandhinimouli: thanks a ton :)

nandhinimouli: sir can u tell me short cut to find a prime number other than divisibility by any prime number less than or equal to the number i.e n^2 >=p where n is smallest counting no. and p is given number

kvnmurty: is the problem like this : p is a prime number. We have to find smallest n such that n^2 >= p.
