Explanation:
If 2 large solar panels = 12 small solar panels
then ? = 6 small solar panels
therefore 6/12 × 2 large solar panels
= 1 large solar panels.
Also
if 2 large solar panels = 18 minutes
than 5 large solar panels = ?
therefore = 5/2 × 180 minutes
=450 minutes
Again
if 2 large solar panels = 180 minutes
than 1 large solar panels = ?
therefore = 1/2 × 180 minutes
= 90 minutes.
