Answer:

The percentage increase in the marks scored by Reena is 10 percent.

Therefore. option (b) is correct.

Step-by-step explanation:

Given,

In July 2019 exam,

The percentage of Reena's score $=\frac{28}{40}\times 100$  =  70%

In September 2019 exam,

The marks of Reena in mathematics  = 32

The total marks of mathematics exam = 40

The percentage of Reena's score $=\frac{32}{40}\times 100$  =  80%                                     The percentage change in the marks scored by Reena = 80 - 70 = 10%
