⇒ x=

3

405

⇒ x=135

⇒ Number of boys in school =8x

=8×135

=1080

Answer 2

Answer:

416

Step by step explanation:

Ratio of no. of boys : Ratio of no. of girls = 8:5

Let no. of boys = 8x

and no. of girls = 5x

Number of girls = 5x = 160

5x = 160

x = 160/5

x = 32

No.of boys = 8x

=8*32

= 256

No. of boys = 256

No. of girls = 160

Total no. of students in school = 256+160 = 416

Therefore strength of the school is 416
