Answer 2

HEY THERE ..!!

HERE IS YOURS SOLUTION;

◆ Assuming that the number of boys & girls are x & y respectively.

So, according to the given data, we get;

x + y = 49. → 1)

&

y = 2 / 5 x → 2)

Solving these equations, we get;

x + y = 49 (→1)

=> y = 49 - x → 3)

Putting value of → 3) in → 2), we get;

49 - x = 2 / 5 x

=> 5 (49 - x) = 2x

=> 245 - 5x = 2x

=> 245 = 7x

=> x = 245 ÷ 7

=> x = 35 = No. of boys in the class

★So, No. of boys in the class is 35★
