Answer Key and Solution:
1. (C)
Let the numbers be x and y .We know   xy = 1575And  x/y = 9/7
We know   xy/x/y = 1575/9/7
We know    y^2  = 1225
We know  y = 35 and x = 45
We know   The sum of the numbers = 45+35= 80
2.(C)

3.(B)

4.(D)
Let the consecutive odd numbers be x and (x+2)We know that x^2 + (x + 2)^2 = 394
We know   x^2 + x^2 + 4x + 4 = 394
We know   2 x^2 +4x – 390 = 0
We know   x^2 + 2x – 195 = 0
We know  (x +15) (x-13) = 0
We know   x = 13  We know    Required sum = 13 +15 =28
5.(D) 
(67^67+ 67) = 67(67^66 + 1) As 66 is an even number
We know   67^66 is an even number
We know   (67^66 + 1) is perfectly divisible by (67 + 1) i.e. 68
We know   The remainder = 67
6.(C)
As 738A6 A is divisible by 11. We know    A + A + 3 = 6 + 8 + 7 We know    A = 9
7.(C)

8.(C)
We know that 3011 * 3012 = 3011 (3011 + 1) = (3011)^2 + 3011
We know    Required least number = 3011
9.(D)
Work done by Q = 19/23 + 8/23 – 1  4/23 
We know   Wage of Q = 4/23 * 5750 = Rs. 1000
10.(B)
Work done by A = 6/24 = ¼  , Work done by B = (x-6)/32
where x is no. of days in which work is competed) We know that ¼ + x – 6/32 + x/64 = 1
We know 16 + 24 – 12 + x /64 = 1  We know 3x + 4 = 64 We know x = 60/3 = 20 days

  3. Bank Jobs vs. SSC Jobs:
    Should i choose bank jobs over ssc jobs This is one of the biggest question that we encounter whenever any notification of SSC is published.

    Infact, there is nothing called SSC jobs since SSC is just an organization like IBPS that fills vacancies in govt. departments through respective selection process.

    Incase if you wish to compare, it should be taken as bank jobs vs. govt. jobs filled through SSC.To answer such a doubt, here is our comparison so everyone can understand & benefit.

    Although banks are owned by Govt. of India, its employees don’t come under the govt. directly like the ones directly employed by Govt.
    Salary hikes/ wage revisions announced by the government are meant for those directly employed by them & NOT for those in public banks.
    Banks decide on salary issue through unions with the govt. (This is the reason for numerous strikes that are held regularly)
    Employees in a bank have to deal with customers daily while its not a necessity in other govt. jobs (except few depts.Finally, bank jobs cannot be compared with those filled through SSC as their profiles, & responsibilities are completely different.

  4. ldc ka descriptive paper sab ko dena hoga jo 2014 me written exam die h

  5. I am appearing for tier 2 for the first time. My exam date is 12th April. Is there exam also on the 11th?

  6. total distance covered= 1000 km
    ==> distance on onward journey = distance on return journey= 500 km
    now let speed in onward journey= x kmph
    so speed in return jouney = 4x/5
    as per question
    500/x + 1/2 + 500/(4x/5) = 23
    solving for x ,, x= 50
    now speed in return journey= 4x/5 = 40 kmph

  7. Divisibility rule
    A number is divisible by 11 if subtraction of sum of odd digits and sum of even digits is a multiple of 11. So result of subtraction may be 0, 11,22,33,…

  8. no need to take x and y etc. here
    just choose an option i tell you
    6/24+(20-6)+20/64=1
    if it becomes one then it is correct answer

  9. Answer and explaination both are wrong for question no 5 answer will be 66 according to binomial theorem
