Answers
Answer:
Answer:
Present Age of Rui Feng is given as = p years old
Case (i): Michael's present age
Michael is given to be 5 years older than Rui Feng
∴ Michael's present age = p + 5
Case (ii): Vishal's present age
Vishal is given to be thrice as old as Michael.
∴ Vishal's present age = 3*[p + 5] = 3p + 15
Case (iii): the sum of their ages in 6 years time
Michael’s age after 6 years will be p + 5 + 6
Vishal’s age after 6 years will be 3p + 15 + 6
∴ Sum of their ages after 6 years = [p + 5 + 6] + [3p + 15 + 6] = 4p + 32
Case (iv): the sum of their ages 3 years ago
Michael’s age 3 years ago will be p + 5 - 3
Vishal’s age 3 years ago will be 3p + 15 - 3
∴ Sum of their ages after 6 years = [p + 5 - 3] + [3p + 15 - 3] = 4p + 14
