Let $x$ kg of good quality wheat should be added.

Acc to ques,

=> $\frac{10}{100} \times x = \frac{5}{100} \times (x + 150)$

=> $10x = 5x + 750$

=> $x = \frac{750}{5} = 150$ kg

Total marks obtained by Matthew

= 42 + 51 + 58 + 35 + 48 = 234

Maximum marks of the five subjects = 5 * 60 = 300

=> Required % = $\frac{234}{3} \times 100$ = 78Â %

Total passengers in train A = 700

=> Total passengers in train B = $\frac{130}{100} \times 700 = 910$

Number of passengers In train AÂ in the class :

General = $\frac{20}{100} \times 700 = 140$

AC = $\frac{1}{4} \times 700 = 175$

Sleeper = $\frac{23}{100} \times 700 = 161$

First = $700 – 140 – 175 – 161 = 224$

Number of passengers in train B in the classÂ :

AC = $480 – 175 = 305$

Sleeper = $\frac{30}{100} \times 910 = 273$

First = $\frac{10}{100} \times 910 = 91$

General = $910 – 305 – 273 – 91 = 241$

Total number of passengers in General Class coaches in both the Trains togetherÂ = 140 + 241 = 381

Total number of passengers in Train-BÂ = 910

=> Required % = $\frac{381}{910} \times 100$

= $41.86 \% \approx 42 \%$

Revenue = consumption $\times$ tax amount

Let consumption = 10 and tax = 10

=> Revenue = $10 \times 10 = 100$

Now, after tax is reduced by 10 %, new tax = $10 – \frac{10}{100} \times 10$

= $10 – 1 = 9$

Total revenue remains unchanged

=> New consumption = $\frac{100}{9}$

$\therefore$ % increase in consumption = $\frac{\frac{100}{9} – 10}{10} \times 100$

= $\frac{10}{9} \times 10 = \frac{100}{9}$

= $11\frac{1}{9} \%$

Let maximum marks in the examination = $100x$

Minimum passing marks = $\frac{64}{100} \times 100x = 64x$

Marks scored by Sujata = $2240$

Acc to ques,

=> $64x + 128 = 2240$

=> $64x = 2240 – 128 = 2112$

=> $x = \frac{2112}{64} = 33$

=> Maximum marks = $100 \times 33 = 3300$

Marks scored by Meena = $2240 – 907 = 1333$

$\therefore$ % marks obtained by Meena = $\frac{1333}{3300} \times 100$

= $40.39 \% \approx 40 \%$

So Sohail’s overall percentage marks-

=$\frac{33+37+28+26+32}{300}$ $\times$100

=$\frac{156}{300}$ $\times$100

=52

Let the Total marks is ‘T’ .

The unreserved guy got 300 but failed by 24 marks i.e. his pass mark is 300 + 24 = 324 .

Given that , the pass mark for unreserved guy is 54% of the total . i.e. $\frac{54}{100}$T = 324.
We get , T = 600 .
Also given that the pass mark for reserved guy is 40% of the total .i.e. {40/100}* 600 = 240.

Here the total subjects are 5 each subject has maximum 70 marks.

So total marks available are 70 Ã— 5 = 350

Total marks of Koel is = 49 + 37 + 45 + 53 + 55 = 239

Percentage of Koel is = $\frac{239}{350}\times100$ = 68.28, which is equal to approximate 68 percent

150 Kg of weight contains 10% low quality weight that is 15 Kg low quality weight.
Let the quantity of good quality wheat to be added be X.
So, $15 = \frac{5}{100}*(150+X)$
Or, $300 = 150+X$

So X = 150 Kg
