Step-by-step explanation:
<h2>[1]</h2>- SI = $250
- Rate (R) = 12
%
- Time (t) = 4 years
Therefore principal is $500.
<h2>__________________</h2><h2>[2]</h2>- 2/7 of the balls are red.
- 3/5 of the balls are blue.
- Rest are yellow.
- Number of yellow balls = 36
Let the total number of balls be x.
→ Red balls + Blue balls + Yellow balls = Total number of balls
Total number of balls is 315.
