Let the required number of days if 14 farmers ploughed = x
| Number of days |
21 |
x |
| Number of farmers |
10 |
14 |
As number of farmers increases, number of days decreases.
∴ They are in inverse proportion
Initially the farmers worked for 21 days. Now they worked for 15 days.
∴ The number of days reduced = 21 – 15 = 6 days
