Two bar diagrams are shown. The top bar diagram is labeled money left after buying mobile. The top bar is labeled 353. The bottom bar is made up of two sections labeled 262 and the letter M. The bottom bar diagram is labeled money now. The top bar is labeled with the letter S. The bottom bar is made up of two sections labeled 10 and the letter M.

To solve this problem using the bar diagram, we need to compare the "money left after buying mobile" bar diagram to the "money now" bar diagram.
In the top bar diagram labeled "money left after buying mobile," we see that the bar is labeled as 353, which represents the initial amount of money Mr. Franks had. After buying the mobile phone, he spent 262 dollars, so the length of the top of the bottom bar in the "money left after buying mobile" diagram is 353 - 262 = 91.
In the "money now" bar diagram, the top bar is labeled with the letter S and does not give any specific value. However, we see that the bottom bar is made up of two sections labeled 10 and the letter M. Since Mr. Franks found $10 in his pocket, the length of the top of the bottom bar in the "money now" diagram is 10.
Comparing the lengths of the top of the bottom bars in both diagrams, we can see that they are equal. Therefore, the missing value labeled with the letter S in the "money now" diagram is 91.
So, Mr. Franks has 91 dollars now, and the correct answer is b. 91.
