Mrs.Diya and her mother-in-law are both school teachers and earn Rs.16,800 and Rs. 10,500 per month respectively. Ratio of distance to the school from their home, to the distance to the school from their colleague John’s home is 2 : 1.
1) If the distance to John’s home from the school is 12 km, what is the distance from school to Mrs. Deewan’s home?

2)If John’s earning twice the income of that of the mother in law, what is the ratio of their wages?

3)Who lives nearer to the school?

i need the correct answer and a proper answer with WORKING or else i will report

Answer 1

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

Step-by-step 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.
