$\underline{\mathfrak{\huge{The\:Question\:asked:}}}$

Richa spent 90 minutes in writing and reading. She spends 20 more minutes in reading than writing. How much time did she spend on each of the activities ?

$\underline{\mathfrak{\huge{Here's \:Your\:answer:}}}$

Let the time spent in writing be = x minutes

Let the time spent in reading be = y minutes

Now, we're given that the Total time spent is = 90 minutes

Thus, we can easily write that :

x + y = 90 [ Let this be equation (1) ]

Also, we're given that the time spent in reading is 20 minutes more than the time spent in writing. So, by this information, we can write that :

y = x + 20 [ Let this be equation (2) ]


Put (2) in (1) :

=》 x + x + 20 = 90

=》 2x = 90 - 20

=》 $\tt{x = 35\:minutes}$

=》 y = x + 20

=》 y = 35 + 20

=》 $\tt{y = 55\:minutes}$
