well final output has become 132%. So if 132 has to reduce to 100, it has to go down to hundred it has to reduce by 32/132*100, ie approx 24.2%

The cyclicity of 3's exponents is 4. ie, the units digits are always in the pattern of 3, 9, 7, 1, 3, 9 and so on and so forth. So multiplying the exponent by 8 and adding 3 to it will always result in the same units digit number. Eg. if n is 1, then 3^11 will result in 7 as the units digit. Likewis...

Statement 1. the tens digit of k+9 is 3 Since the units digit is not 0, even if the units digit is the lowest i.e. 1, adding 9 to the number will affect the tens digit. Hence the tens digit of k is 2. SUFF 2) the tens digit of k+4 is 2 If the units digit of k is 6 or greater, the tens digit of k+4 w...

only D is relevant because it says that the hotel can cut its losses by getting rid of mini-bars.

the 28th exponent of 7 will have the units digit as 1.
The 23rd exponent of 3 will have units digit as 7.

Therefore (1-7) = 4

Answer is C

Here's my approach. (1 - prob of picking no pairs) The probability of picking the first card is 1. The prob of picking the second card that is not a pair of the 1st card is 10/11 The prob of picking the 3rd card which is not a pair of the 1st and 2nd card is 8/10 The prob of picking the 4th card tha...
