According to the question,
First we have to calculate the total number of students appearing from School U in 2017
Number of Boys in U = 44%%
That means number of girls will be= 56%
Difference = 12%
As per the table, the difference is 45
12% = 45
1% = 45/12
= 3.75
Total students = 100% = 375
Now we have to calculate the total number of students appearing from School R in 2017
Number of boys = 44%
That means number of girls = 56%
Difference = 12%
As per the table, the difference is 30.
12% = 30
1% = 30/12
= 2.5
Total students in R = 100% = 250
Determining the value of percentage = 375/250 x 100 = 150
Hence, '150' is the correct answer.
