Question

The marks of all the students in the math class were released by the professor. James scored 78.87 %, Robert scored 93.12%, and Rosy scored 93.43 %.
Who among the three students got the highest score?

• A. James
• B. Robert
• C. Rosy

Answer 1

The correct option is C Rosy

Let's arrange the numbers 78.87, 93.12, 93.43 on the Place value table. Names H O . t h James Robert Rosy

7	8	.	8	7
9	3	.	1	2
9	3	.	4	3

$\Rightarrow$ Compare the digits in the hundreds place: 7 < 9
In the hundreds place, 7 is smaller than 9, hence the decimal 78.87 is the smallest of the three numbers.

$\Rightarrow$ Let's compare 93.12 and 93.43
In both 93.12 and 93.43, the digits in the ones and tens place are the same.

$\Rightarrow$ Hence, compare the digits in the tenths place: 93.12 and 93.43
As 4 > 1, 93.43 > 93.12

$\therefore$ 93.43 > 93.12 > 78.87
Rosy scored the highest marks.
