उत्तर
| Commodity | Base year price (in ₹) p0 |
Current year price (in ₹) p1 |
| P | 10 | 14 |
| Q | 8 | 10 |
| R | 12 | x |
| S | 24 | 28 |
| T | 18 | 22 |
| Total | 72 | 74 + x |
From the table, `sum"p"_0` = 72, `sum"p"_1` = 74 + x
P01 = `(sum"p"_1)/(sum"p"_0) xx100`
125 = `(74 + x)/72 xx 100`
∴ `(74 + x)/72 = 125/100`
∴ 74 + x = `5/4 xx 72`
∴ x = 90 – 74
∴ x = 16
