Hi there!
Here's the answer:

°•°•°•°•°<><><<><>><><>°•°•°•°•°

In a class,
Let the No. of boys = 7x
and No. of girls = 5x

Given,
No. of boys = 35
=> 7x = 35
=> x = 5

•°• No. of girls 5x = 25

°•°•°•°•°<><><<><>><><>°•°•°•°•°

Verification:

Total No. of boys and girls = 35+25= 60
Ratio of no. of girls and boys =7 : 5

No. of boys = [7/(7+5)] × 60 = 35
No. of girls = [ 5/(7+5)] × 60 = 25
Data matched
