Previous year questions give guidance to us and provide a base for the preparation of any competitive exam. It is always good to have an experience of how the level of exam varies from year to year. For every subject like in Quantitative Aptitude, we come to know the pattern of questions must be followed to prepare the examination.

on overall transaction. Find the cost price of cheaper article.
(1.) 1640 (2) 1656 (3)
1660 (4) 1680 (5) 1696
Sol
Let S.P. = x
2.) An election is conducted between two candidates in a
city. 50000 enrolled voters did not cast their votes and only 80% of cast
voters were valid. If the winning candidate won by 12200 votes, the losing

Let the total number of voters be x
Total votes cast =

10 (4) 12 (5) 15
Sol
I III II III
30
50 38 50
40 40
10 10 10 2
1 : 1
5 : 1
I : II : III = 1 : 5 : (1+1)
2--- 4kg
5--- 10 kg

(1.) 5 (2) 8 (3)
10 (4) 12 (5) 15
Sol
S1:
S2 = 2 : 3
2x + 3x = 50×2
S1
= 2x = 40
5.) Annu and Bhanu work together, to complete a piece of
work in 12 days. If Annu starts the work and leave after he complete half of
