Answer:
1. the distance from the school to Mrs Deewan's home = 24km
2. John's wage to the mother-in-law's wage = 2:1
Mother-in-law's wage to John's = 1:2
3. John lives nearer the school
Explanation:
1. The ratio of the distance between Mrs Diya's (Deewan's) home and John's home to school = 2:1.
This means that the distance of Mrs Diya's home is twice that of John's home to school. Therefore if John's home from school is 12km;
Mrs Diya's home = 12 × 2 = 24km
2. If john earns twice the income of the mother-in-law, the ratio of the wages is as follows:
John's wage to the mother-in-law's wage = 2:1
Mother-in-law's wage to John's = 1:2
3. John lives nearer the school. From the calculation we've done in 1 above, you can see that the distance between John's home and the school = 12km, while the distance between Mrs Diya's home and the school is 24km, therefore, John lives nearer the school.
