suman studies for 5whole 2upon 3 hours daily.she devotes 2whole4opon5hours of her time for science and mathematics.How much time does she devote for other subject​

Answer 1

Answer:

Let the hours Suman studied other subject be x .

⇒ $2\frac{4}{5} + x = 5\frac{2}{3}$

⇒ $\frac{14}{5} + x = \frac{17}{3}$

⇒    $x$      $=$  $\frac{17}{3} - \frac{14}{5}$

⇒    $x$      $=$  $\frac{85 -42}{15} = \frac{43}{15} = 2\frac{13}{15} ANS$

Suman studies $2\frac{13}{15}$ hrs other subjects daily .
