  • MATHS(PART B)
The average temperature  of three days is  24 o c  .if  temperature  on  the  first two  days  is  20  o c  and  25 o  c  respectively then  the  temperature  on  the  third  day
a 22  ½    b 23   c 27   d 24

   The total temperature recorded on three days   was 24*3=72
   First two days  temperature     20+25  = 45
   Then last days temperature  is   72-45=27

  So  Answer  is  c  27
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
Therefore 25x + 30x = 110
55x = 110
X=55/110
X=2  
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

Solved question -PA/SA Exam held on 12.05 2013
A sum of Rs 8000 generates Rs 1261 as compound interest in 3 Years . Interest being compound annually . The rate of compound interest is 
a 20 % b 2.5 % c 10 % d 5 % 
r = ( FV / PV )1/n – 1

r= RATE OF INTEREST ?
FV = FUTURE VALUE 9261
PV = PRESENT VALUE 8000

Three items are purchased at Rs 380 each . One of them is sold at a loss of 10% . The others are sold so as to gain 25% on the whole transaction ? what is the gain % on these two items

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%
