Hence,(1- 3/4) of (2/3)X is remainingi.e. (1/4)(2/3)X = (1/6) XHence 1/6th of the contents of the container is remaining2)Vipul studied for 3 hours in candle light.Assume that the initial lenght of both the candle was L and Vipul studied for X hours.In X hours, total thick candle burnt = XL/6In X hours, total thin candle burnt = XL/4After X hours, total thick candle remaining = L - XL/6After X hours, total thin candle remaining = L - XL/4Also, it is given that the thick candle was twice as long as the thin one when he finally went to sleep.(L - XL/6) = 2(L - XL/4)(6 - X)/6 = (4 - X)/2(6 - X) = 3*(4 - X)6 - X = 12 - 3X2X = 6X = 3Hence, Vipul studied for 3 hours i.e. 180 minutes in candle light.3)Rs.333,062,500To begin with, you want to know the total number of days: 365 x 50 = 18250.By experimentation, the following formula can be... | | By: Technical Interview Questions | | |

| Answers for Practise Puzzles - 2 | | 2008-07-30 10:08:22 | | 1)The required number is 236 and the sum is 11.It is given that the first two digits of the required number are prime numbers i.e. 2, 3, 5 or 7. Note that 1 is neither prime nor composite. Also, the third digit is the multiplication of the first two digits. Thus, first two digits must be either 2 or 3 i.e. 22, 23, 32 or 33 which means that there are four possible numbers - 224, 236, 326 and 339.Now, it is also given that - the difference between it's reverse and itself is 396. Only 236 satisfies this condition. Hence, the sum of the three digits is 11.2)A=2, B=1, C=9, D=4, E=3, F=8, G=6, H=5, I=7Let's start with GHI = 9 * IE. Note that I appears on both the side. Also, after multiplying IE by 9 the answer should have I at the unit's place. The possible values of IE are 19, 28, 37, 46, 55, 64, 73, 82 and 91; out of which only 64, 73 and 82 satisfies the condition. (as all alphabet should represent different digits)Now, consider DEF = 6 * IE. Out of three short-listed values, only 73 sat... | | By: Technical Interview Questions | | |

Each can be arranged in 2P2 = 2! ways.Hence, the require answer is= (16!) / (8! * 2! * 2! * 2!)= 6,48,64,8002)Rs. 250/-Assume that initially he had Rs. XHe spent 1/3 for cloths =.
