Verified by Toppr

Correct option is A. 170
Let us prepare a chart of the $$100$$ students using the data from the bar graph.
Marks Number of Students
$$0 − 9$$ $$27$$
$$10 − 19$$ $$12$$
$$20 − 29$$ $$20$$
$$30 − 39$$ $$24$$
$$40 − 49$$ $$17$$
Highest marks group $$= 40 − 49$$
Number of students in this marks group $$= 17$$
$$\therefore\,$$ Required money to distribute the prize $$=\ Rs. 10 \times 17 =\ Rs. 170$$
