Solution

The correct option is D $50$ minutes
Time spent while talking to Rishita
= $\frac{1}{3}$ hour
= $\frac{1}{3} \times 60$ minutes
= $20$ minutes.

Time spent while talking to Deepika
= $\frac{1}{2}$ hour
= $\frac{1}{2} \times 60$ minutes
= $30$ minutes.

So, time spent on mobile phone
= $20 + 30$ minutes
= $50$ minutes
