# Quantitative Aptitude: Simplification Questions Set 1

1. 22% of 350 + 35% of 420 = 16% of 250 + x
A) 184
B) 144
C) 136
D) 196
E) 148
Option A
2. 1 1/4 + 2 4/5 + 3 5/8 + 2 3/10 = x
A) 10 19/40
B) 9 17/30
C) 9 19/25
D) 8 29/35
E) 9 39/40
Option D
Solution:
1 1/4 + 2 4/5 + 3 5/8 + 2 3/10
[1 1/4 + 3 5/8] + [2 4/5 + 2 3/10]
[1 + 3 + 1/4 + 5/8] + [2 + 2 + 4/5 + 3/10]
[4 + 11/10] + [4 + 7/8]
[4+ 4 + 11/10 + 7/8]
[8 + 79/40] = 9 39/40
3. 1008 ÷ 16 × 3/7 + 19 × 204 = 13 × 15 + x
A) 5327
B) 3099
C) 3476
D) 5376
E) 3708
Option E
Solution:
1008 ÷ 16 × 3/7 + 19 × 204 – 13 × 15
1008/16 × 3/7 + 3876 – 185
27 + 3876 – 185
4. (0.6)5/4 ÷ (0.36)3/8 × (0.3)13/12 ÷ (0.09)7/24 = (0.18)1-x
A) – 1/2
B) 1/2
C) – 4/3
D) 1/4
E) 5/6
Option B
Solution:
(0.6)5/4 ÷ (0.36)3/8 = (0.6)5/4 ÷ (0.6)2 * 3/8 = (0.6)5/4 ÷ (0.6)3/4 = (0.6)5/4 – 3/4 = (0.6)1/2
Similarly, (0.3)13/12 ÷ (0.09)7/24 = (0.3)1/2

So (0.6)1/2 × (0.3)1/2 = (0.18)1/2
So (0.18)1/2 = (0.18)1-x gives 1/2 = 1 – x, So x = 1/2
5. 1 1/2 + 2 2/3 + 3 1/6 + 4 3/8 = x
A) 11 8/15
B) 10 5/21
C) 11 17/24
D) 12 3/10
E) 10 13/21
Option C
6. (0.4)17/16 ÷ (0.16)3/32 × (0.3)5/4 ÷ (0.09)3/16 = (0.12)x
A) 7/8
B) 1/5
C) 7/5
D) 9/13
E) 6/11
Option A
Solution:
(0.4)17/16 ÷ (0.16)3/32 × (0.3)5/4 ÷ (0.09)-3/16
= (0.4)7/8 × (0.3)7/8
7. 3 9/14 × 1 4/17 × 2 16/18 – 2 3/4 = x
A) 11 1/3
B) 8 2/4
C) 10 1/6
D) 9 1/5
E) 10 1/4
Option E

any short approach for ques. 7 ??

1. !!angry bird !!

no sir 🙁

2. Ankush Choudhary

yes…..do it by solving the fraction and relate with the nearby fractions in the option

1. ครђ

1. Ankush Choudhary

yes why not…
see its hard to take LCM of the terms and then to solve it( normal approach) .
to make it a bit easier solve the fractions, for example-> take this case 23/7 + 91/3 = 3.3+30.3= 33.6………and now relate this answer with fraction given in the options………as 33.6 is close to 102/3….it would be hard if you take LCM of 3,7 and then solve it…….hope its clear now..

2. ครђ

It is the soltution of ques 7. na??

28. Another thing I have really noticed is the fact that for many people, low credit score is the reaction of circumstances over and above their control. For instance they may have been saddled with an illness and because of this they have excessive bills for collections. Maybe it’s due to a job loss or the inability to work. Sometimes divorce proceedings can really send the funds in the wrong direction. Thank you for sharing your thinking on this blog site.
