Answer 1

Step-by-step explanation:

let total no. of first exam be 100

as she scored 30%

so 30%of 100 = 30

she scored 30 marks in first exam

now,

according to question she needs 36% of total of two exams

total no. = as we took 100 as marks so two exams

=100×2 = 200

she already secured 30 marks in first exam

so 30 is persent of 200 =

$\frac{30}{200 } \times 100 = 15\%$

she needs 36 % of 200 marks

so she needs = 72 marks totally

now she scores 30 marks in first exam

she wants in second exam

$72 - 30$

=41
