(ii) Vishal's present age, 3 p + 15

(iv) the sum of their ages 3 years ago. 5 p +1) 7ur 2 1134-6) -​

Answer 1

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
