Answers & Solutions:

1) Answer (D)

$\frac{3}{8}$ of $((4624 \div (564-428))=?$

$\frac{3}{8}$ of $((4624 \div (136))=?$

$\frac{3}{8}$ of $(34)=?$

$\frac{51}{4}$

12$\frac{3}{4}$

 

2) Answer (D)

? =456 ÷ 24 × 38 – 958 ÷ 364 × 182

? =19 × 38 – 958 ÷ 2

? =19 × 38 – 479

? = 722 – 479

? = 243

 

3) Answer (D)

The total percentage of her salary that Sujata invested is 7% + 18% + 6% = 31%

7% of her salary is Rs. 2170.
So, 31% of her salary is 2170/7 * 31 = 9610

So, Sujata invests Rs. 9610 every month i.e 9610*12 = 115320

4) Answer (D)

$\frac{2}{5} \times 2500 = 1000$
So, 40% of 1000 = 400
30% of 400 = 120

5) Answer (B)

Let the speed of women be x and that of children be y. Let the piece of work be W.
2x + 10y = W/8
8x = W/6
x = W/48
Hence, we get y= W/120
Speed of 1 child = W/120
Speed of 10 children = W/12
Now time needed for them to complete = W/(W/12) =12days
Therefore, the correct option is B.

6) Answer (E)

10 women can complete the work in 8 days. So, number of hours required for 1 woman to complete the work = 80

Number of hours required by one child to complete the work = 120

So, 80W = 120C => 1W = 1.5C

6 women + 3 children = 9 children + 3 children = 12 children

So, 12 children take 10 days to complete the work.

7) Answer (E)

$960 – 11^2 = 839$

$839 – 9^2 = 758$

$758 – 7^2 = 709$

$709 – 5^2 = 684$

$684 – 3^2 = 675$

Hence, the missing number is 684

8) Answer (B)

For first, third, fifth and seventh number:

61-1 = 60

60-1 = 59

59-1 = 58

For fourth and sixth number:

72+1 = 73

73+1 = 74

Hence, answer will be B

9) Answer (A)

Circular permutation = n! (n – 1)!

∴ Number of ways = 6! (6 – 1)! = 6! × 5!

10) Answer (B)

Word name: ‘JOKE’ Vowels: O, E
Consonants: J, K
∴ Possible arrangement beginning with consonant: JOKE, KOJE, JEKO, KEJO = 4 Numbers
beginning with vowel: OJEK, OKEJ, EJOK, EKOJ = 4 Numbers
Required number = 4+4 = 8 numbers

11) Answer (A)

Cost price of both A and B be X.
SP of A = 1.14 CP of A
SP of B = CP of B + 4290
Net profit after selling both bikes is 20%
1.2 (X+X) = SP of A +SP of B
1.2 (X+X) = 1.14 CP of A + CP of B + 4290 = 1.14X + X + 4290
2.4X = 2.14 X + 4290
0.26 X =4290
X = 16,500
Option A is the correct answer.

12) Answer (A)

Total revenue generated by selling variety A rice = 1.1*15x = 16.50x
Total revenue generated by selling variety B rice = 1.2*10(x+5) = 12x + 60

It is given that, 16.5x – 12x – 60 = 30
$\Rightarrow$ x = 20.

When the two varieties been mixed and sold at an overall profit of 20%. Total weight of the entire mixture = 10+15 = 25 kg.
Total cost price of the mixture = 15*20 + 10*25 = 550
Therefore, the cost price pf the mixture per kg = \dfrac{550}{25} = Rs. 22 per kg.
It is known that the mixture was sold at 20%. Therefore, the selling price of the mixture = 1.2*22 = Rs. 26.40.
Hence, option A is the correct answer.

13) Answer (E)

The required percent = (Number of females/Number of males)*10 = (57+79+24)/(56+86+35)*100=(177/166)*100=110

14) Answer (C)

Total number of student is addition of all the students doing all the specialization = 18+28+67+25+26+85+25+35+64+85= 572

15) Answer (B)

Perimeter of square field = 784 ft.

Radius of circular field = Side of square field = $\frac{784}{4}$ = 196 ft.

Area of circular field = $\pi r^2 = \frac{22}{7}\times196\times196 = 120736$ sq ft
