Answer 1

Answer:

Let the present age's of mother be 'M' and that of her son be 'S'.

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2)

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2)

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2) From (1) & (2), we get

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2) From (1) & (2), we getS = 20

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2) From (1) & (2), we getS = 20Then by substituting S = 20 in (1) or (2), we get

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2) From (1) & (2), we getS = 20Then by substituting S = 20 in (1) or (2), we getM = 50.

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2) From (1) & (2), we getS = 20Then by substituting S = 20 in (1) or (2), we getM = 50.

Let the present age's of mother be 'M' and that of her son be 'S'.According to the given data in the question,M - 5 = 3(S - 5)F - 3S = -10 ...............(1)Then given ,M + 5 : S + 5 = 11 : 5 => 5M - 11S = 30 ..............(2) From (1) & (2), we getS = 20Then by substituting S = 20 in (1) or (2), we getM = 50. Hence, the present age of mother is M = 50 years.
