a 22  ½    b 23   c 27   d 24

   The total temperature recorded on three days   was 24*3=72

Two  trains  leave  stations  p  and  q 110  km  apart  train  from  p  and  q  travels  at 25 km/hr and  train  from  q to  p  at  30 km/hr  if they  both  start  at  8 AM  they  meet at
a  10.40 AM    b  09.00 AM  c 8.45 AM   d  None  of these ,
Suppose they meet x hours after 8  a.m.
Distance covered by P  in x hours = 25x km.
Distance covered by q  in  x  hours = 30xkm
 25x + 30x = 110
55x = 110
they meet at 10 a.m.
So  Answer  d   None  of  these

The average score of  Sachin Tendulkar in  IPL  15  Matches is 70  Runs and the  average score in  Border Gavaskar Trophy  T-20  Matches  is 45 runs in  7  Matches .

a 990 b 971  c 982 c None  of these

 If he  has played 10  more  international T-20  matches and his  overall  average  score  in T-20 Matches was 73 runs .

what was  his   total  score  in  10  international T-20  Matches 

  Average  score in  15  matches   is  70    so  total scored    in 15   Matches    15*70=           1050

  Average  score in  7  matches   is  45    so  total scored    in  7   Matches    7*45=  1050=      315
          If he played  10  more  match then  t-20  matches average will  become  73

Ie  total matches  played   15+7+10= 32 
                                                                          73=   1050+315+x/32

                                                                          73= 1365x/32

                                                    73*32=1365x= 2336=1365x
   .’.    x=2336-1365=  971    ie  2336/32= 73

So   Answer is   b  971

a 44.5 % b.42.5 % c 40.5 % d None of these 

Cost price = 380*3 = 1140

If 25 % is gain is needed then 

our target SP of total goods = 125/100×1140=Rs.1425

cost price of one item is Rs 380

SP of one item = 90/100×380=Rs.342

SP of the remaining goods = 1425 – 342 = Rs. 1083

Cost price of two items = 380*2= 760
323/760*100= 42.5 % 
So Answer is b 42.5%
