Heya user,
(11)---> By pigeon hole principle, 1st Answer = (C)
If we choose 4 swords, chances are---> we get three different swords but the fourth one is Similar to either of those
(12) --> 90/100 P = 30/100 Q => Q = 3P
=> Q is 300% of P..
(13) Let the weights be ( 51 + x ), ( 51 + y ), ( 51 + z )
Then, Avg. => 153 + ( x + y + z ) = 53 * 3 = 159
=> ( x + y + z ) = 6
Assuming x, y as 0; z = 6
Hence greatest weight = 51 + 6 = 57 kg.
(14) ---> Area = 5*7 = 35 sq. cm
=> Cost = 35 * 10 = Rs. 350
(15) ---> Letters are Coded as ( -1 )
.'. New York ---> MDV XNQJ
(16) ---> 30/100 * x = 15 => x = 15/30 * 100 = 50
Hence, 15 is 30% of 50
(17) ---> By Basic Counting Principle, my position from front = 6th, and from back = 7th
Hence, no. of people in the queue = 6 + 7 -1 = 12
(18) ---> Since the no. of eggs is doubling each minute, it takes 59 minutes to fill half basket so that the last minute it doubles to Full Basket
(19) ---> Actually, we are being given the discount,
.'. 20% of x = Rs. 15 => x = Rs. 75.
And hence, the Actual Price paid = Rs. 75
(20) ---> Since, the percentage of Fails are A∪B = 40 + 30 = 70%
.'. The percentage passed ---> 30%
