Answers & Solutions:

1) Answer (A)

Total mixture of sand and iron = 1 kg

Quantity of iron = $\frac{20}{100} \times 1 = 0.2$ kg

Let $x$ kg of sand should be added, thus total iron in the mixture

=> $0.2=\frac{10}{100} \times (x+1)$

=> $2=x+1$

=> $x=2-1=1$ kg

=> Ans – (A)

2) Answer (D)

Let P has = $Rs. 100x$

=> Amount with Q = $100x + \frac{25}{100} \times 100x = Rs. 125x$

=> Amount with R = $\frac{1}{5} \times 125x = Rs. 25x$

Total amount together = $100x + 125x + 25x = 150$

=> $x = \frac{150}{250} = \frac{3}{5}$

=> $x = 0.6$

$\therefore$ Amount with P alone = $100 \times 0.6 = Rs. 60$

3) Answer (C)

Let us rank the person according to the marks scored by them, where 1 -> highest marks and 5 -> lowest marks.

Only one person scored less marks than B, => B = 4

Also, A > D > B and $A \neq 1$

=> A = 2 and D = 3

Thus, ranking from 1-5 = C/E , A , D , B , E/C

$\therefore$ A scored the second highest marks.

4) Answer (D)

Amount with A = $Rs. 4x$

=> Amount with C = $\frac{3}{4} \times 4x = Rs. 3x$

=> Amount with B = $Rs. (3x – 50)$

Total amount with A,B & C = $4x + 3x + (3x – 50) = 250$

=> $10x = 250 + 50 = 300$

=> $x = \frac{300}{10} = 30$

$\therefore$ Amount with A = $4 \times 30 = Rs. 120$

5) Answer (D)

Total amount = 97836

No. of children = 31

Since amount is distributed equally

=> Amount each child will get = $\frac{97836}{31}$ = Rs. 3,156

6) Answer (E)

There are 30 students and 2 teachers.

Sweets received by each student = $\frac{20}{100} * 30$ = 6

=> Total sweets received by all the students = 30 * 6 = 180

Sweets received by each teacher = $\frac{30}{100} * 30$ = 9

=> Total sweets received by both teachers = 2 * 9 = 18

$\therefore$ Total sweets distributed in class = 180 + 18 = 198

7) Answer (B)

Let the cost of a folder = Rs. $x$

and cost of a pen = Rs. $y$

=> $20x + 15y = 995$

Multiplying the above equation by $(\frac{3}{5})$, we get :

=> $\frac{3}{5} \times (20x + 15y = 995)$

=> $12x + 9y = 597$

$\therefore$ Cost of 12 folders and 9 pens is Rs. 597

8) Answer (B)

Let the cost of a note-book = Rs. $x$

and cost of a pen = Rs. $y$

=> $12x + 16y = 852$

Multiplying the above equation by $(\frac{3}{4})$, we get :

=> $\frac{3}{4} \times (12x + 16y = 852)$

=> $9x + 12y = 639$

$\therefore$ Cost of 9 note-books and 12 pens is Rs. 639

9) Answer (B)

Let the cost of a chair = Rs. $x$

and cost of a table = Rs. $y$

=> $10x + 15y = 15525$

Multiplying the above equation by $(\frac{4}{5})$, we get :

=> $\frac{4}{5} \times (10x + 15y = 15525)$

=> $8x + 12y = 12420$

$\therefore$ Cost of 8 chairs and 12 tables is Rs. 12,420

10) Answer (C)

Case I : Trader sells 150 metres of cloth for Rs. 6,600

=> S.P. per metre = Rs. $\frac{6600}{150}$

= Rs. 44

Case II : Trader sells 300 metres of cloth for Rs. 12,750

=> S.P. per metre = Rs. $\frac{12750}{300}$

= Rs. 42.5

$\therefore$ Required discount = Rs. (44 – 42.5) = Rs. 1.5

11) Answer (E)

C.P. of 1 pen = Rs. $x$

C.P. of 1 pencil = Rs. $y$

=> $20x + 17y = 418$

Multiplying above equations by 3

$\therefore$ $60x + 51y = 1254$

12) Answer (A)

Cost of 36 pens and 42 pencils = 460

Dividing by 2, we get :

=> cost of 18 pens and 21 pencils = $\frac{460}{2}$ = Rs. 230

13) Answer (C)

Let fraction be $x$

Ram’s correct answer should be = $\frac{7}{8}x$

Ram’s actual answer = $\frac{x}{\frac{7}{8}}=\frac{8}{7}x$

Difference = $\frac{8x}{7}-\frac{7x}{8}=\frac{75}{784}$

=> $\frac{(64x-49x)}{56}=\frac{75}{784}$

=> $15x=\frac{75}{784}\times56$

=> $x=\frac{75}{14}\times\frac{1}{15}$

=> $x=\frac{5}{14}$

$\therefore$ Ram’s correct answer should be = $\frac{7}{8}\times\frac{5}{14}=\frac{5}{16}$

=> Ans – (C)

14) Answer (B)

Let capsules bought = $x$

Acc. to ques,

=> $\frac{176}{x} – \frac{176}{x + 6} = 3$

=> $\frac{176 \times 6}{x (x + 6)} = 3$

=> $x (x + 6) = 352 = 22 \times 16$

=> $x (x + 6) = 16 (16 + 6)$

=> $x = 16$

15) Answer (C)

Let the number of days in which employee was absent = $x$

=> Days in which he was present = $(56 – x)$

Acc. to ques,

=> $(56 – x) \times 26 – 7x = 829$

=> $1456 – 26x – 7x = 829$

=> $33x = 1456 – 289 = 627$

=> $x = \frac{627}{33} = 19$

16) Answer (E)

Let the first and second numbers resp be $x$ and $y$

=> $\frac{35}{100} x = \frac{75}{100} y \times 2$

=> $35x = 150y$

=> $\frac{x}{y} = \frac{30}{7}$

17) Answer (C)

Cars manufactured in 8 days = 96 dozen

Cars manufactured in 17 days = $\frac{96}{8} \times 17$

= 204 dozen

18) Answer (B)

Let the cost of a fan = Rs. $x$

Cost of an oven = Rs. $y$

=> $8x + 14y = 36520$

Multiplying both sides by $(\frac{3}{2})$, we get :

=> $\frac{3}{2} \times (8x + 14y = 36520)$

=> $12x + 21y = 54,780$

19) Answer (B)

Let the maximum marks in the examination = $100x$

Acc. to ques,

=> $\frac{2}{100} \times 100x = 280 – 264$

=> $2x = 16$

=> $x = \frac{16}{2} = 8$

=> Max marks = 8 * 100 = 800

$\therefore$ Passing percentage = $\frac{280}{800} \times 100$ = 35 %

20) Answer (A)

Let CP of 1 chair = Rs. $x$

and CP of 1 table = Rs. $y$

Now, $8x = 5y$

and $6x + 2y = 3680$

Solving above equations, we get

$x = 400$ and $y = 640$

$\therefore$ Cost of 6 tables = 6*640 = Rs. 3840
