which year? link...Awesome12 Q:21 from the same paper.
(a) The tens digit cannot be less than 2 and there's no zero so it has to be greater than 20.Awesome12 Q:21 from the same paper.
(b) First digit has to be 3 probability of choosing it is 2/6 and for second its 1/5 as only one is left and total remaining are 5. Multiply them and you get 1/15.
(c) For 43 first digit has to be 4 so its probability is 3/6 and for second digit 3 its 2/5 as number of 3's is same. For 32 its 2/6 for first 3 and 1/5 for the 2. Multiply them and you get 3/15 and 1/5 respectively. Add both and 4/15 is the final answer.
Kevin's speed = d /T
d = Kevin's speed * T
Jane's speed is 1o % faster than Kevin (ie. Jane's speed = Kevin's speed * (110/100) )
Jane's speed (i.e Jane's speed = Kevin's speed (d/T) * (110/100)) = d/t
d ......... 110 ....... d
--- * ------ = ----
T ........ 100........ t
Find t
