x+2/5x=49

7/5x=49

x=35

no: of boys are 35

Answer 2

Answer:

There are 35 boys in the class

Step-by-step explanation:

Let the no. of boys be = x

No. of girls be = 49 - x

So, Now

$= \frac{2}{5}x = 49 \times 5 \\ = \frac{2}{5}x + x = 49 \frac{ - 2x + 5x}{5} = 49 \\ = 7x = 49 \times 5 \\ = x = \frac{49 \times 5}{7} = 35 \: ans.$

• So, the no. if boys is 35
