Question

(Look at the graphs for questions 1 and 2.)

Answer 1

Solving Q1 : What is y when x = 50? (the solution graph is attached below)

We can make a rectangle (in red color on solution graph) to find the value of y corresponding to x = 50. We can see that y-value lies between 200 and 250.

It is near about y = 225. Hence, option B is correct.

Solving Q2 : What is x when y = 300? (the solution graph is attached below)

We can make a rectangle (in red color on solution graph) to find the value of x corresponding to y = 300. We can see that x-value lies between 60 and 65.

It is near about x = 61. Hence, option A is correct.

Solving Q3 : Solve 17x = 3.

$17x = 3 \\\\ x = \frac{3}{17} \\\\ x = 0.176470588 \approx 0.18$

Hence, option A is correct i.e. x = 0.18
