Consumption of wheat in family B in Jan = 20 kg
Consumption of wheat in family A in Jan = (2 * 26) - 20 = 32 kg
Consumption of wheat in family A in Feb = 56 - 32 = 24 kg
Consumption of wheat in family B in Feb = 24 * (2/3) = 16 kg
Consumption of wheat in family C in Feb = 70 - 24 - 16 = 30 kg
Consumption of wheat in family C in Jan = 30 + 8 = 38 kg
| Months | Family A | Family B | Family C |
| Jan | 32 | 20 | 38 |
| Feb | 24 | 16 | 30 |
Consumption of wheat in family B in Jan = 20 kg
Consumption of wheat in family C in Jan = 38 kg
Required percentage = [(38 - 20)/20] * 100 = 90%
