Answer 1

Answer:

C.33.33%

Step-by-step explanation:

as the salary %of Prakash is 30%

Answer 2

By 66.67% the salary of Prakash  is more than that of Akash. Thus Option B is correct

Solution:

The salary of Akash, Bikash and Prakash are in the ratio 3:2:5

Let salary of Akash = 3x

Salary of Bikash = 2x

Salary of Praksh = 5x

The total salary Akash and Bikash together is Rs 7,000

So,   3x + 2x = 7000

5x = 7000

x = 7000 ÷ 5 = 1400

Now the respective salaries are:

Salary of Akash = 3x = 3(1400) = 4200

Salary of Bikash = 2x = 2(1400) = 2800

Salary of Praksh = 5x = 5(1400) = 7000

To find by what percent salary of prakash is more than that of Akash:

$= \frac{prakash salary - Akash salary}{Akash Salary} \times 100$

$=\frac{7000-4200}{4200} \times 100=\frac{2800}{4200} \times 100=66.67 \%$

Hence the answer is 66.67% Thus Option B is correct
