Last Updated On: Fri Aug 28 2026| Product | Units sold | Share of total |
|---|---|---|
| P | 150 | 30% |
| Q | ? | 25% |
| R | 225 | ? |
| Total | ? | 100% |
A "?" marks a missing value.
Question
Find the total units sold, the units of Q, and the share of R.
Solution
- P is 30% of the total, so total = 150 / 0.30 = 500.
- Q = 25% of 500 = 125 units.
- R's share = 225 / 500 x 100 = 45%.
- Check: 30% + 25% + 45% = 100% and 150 + 125 + 225 = 500.
