Answer 2

Answer:

Rs.4200

Step-by-step explanation:

Let the initial cost be x .

We are given that after $16\frac{2}{3}\%$ in the cost of machine .It becomes Rs. 4900

Increment % =  $16\frac{2}{3}\% = \frac{50}{3}\%$

Increment = $\frac{50}{300}x$

Cost after increment =  $x+\frac{50}{300}x=\frac{350x}{300}$

ATQ

So, $\frac{350x}{300} = 4900$

$350x= 4900 \times 300$

$x=\frac{ 4900 \times 300}{350}$

$x=4200$

Hence the initial cost is Rs.4200
