After first discount Marked Price (MP) become,
= 920 - 15% of 920 = 782.
The Selling Price (SP) = 742.90.
Let second discount was x% on 782.
782 - x% of 782 = 742.90
782x/100 = 39.1

] | D | Total number of cards = 52
Total Number of King Cards = 4
P(King) = 4/52
P(Diamond) = 13/52
P(King and Diamond) = 1/52
P(King or a Diamond) = P(King) + P(Diamond) – P(King and Diamond)
=4/52+13/52–1/52=16/52=4/13

] | A | Speed = 54 x 5/18 m/sec = 15 m/sec.
Length of the train = (15 x 20)m = 300 m.
Let the length of the platform be x metres.
Then, (x + 300)/31 = 15
x + 300 = 465
x = 165 m.Answer: Option A |

] | B | Let the present ages of Giri and Hari be 5x and 8x years respectively.
(5x + 12) / (8x + 12) = 11/14
70x + 168 = 88x + 132 => x= 2
Difference in their ages will be the same at all times.
This difference = Difference of their present ages
= 8x - 5x = 3x = 6 years.
