Question

four times sunil age decreased by 3 equal to three times has age increased by. how old is sunil​

Answer 1

Answer:

Let the age of Sunil = x

by the statement, Father is aged three times more than his son Sunil.

we can write

Father age = 3x

Now after 8 years

son’s age will be x+8

father’s age will be 3x (original age) + 8 ( after 8 years)

2.5(x+8) = 3x+8 - - - - - 2.5 of son’s age is father after 8 years

opening the brackets

2.5x+20=3x+8

20–8=3x-2.5x

12=0.5x

x=12/0.5

x=24

Sons’s age is 24. Father’s age is 24 x 3 = 72 years - - - - - - (statement 1)

After further 8 years age will be

Son will be 24 + 8 = 32

Father will be 72+8 = 80

After further 8 years age will be

Son will be 32 + 8 = 40

Father will be 80+8 = 88

( We need to add the factor of 8 years twice because in statement 1 what we have figured is the present age, but in the question, the relation asked is when the ages are calculated after 8 + 8 total 16 years )

Question asked is the father is how many times greater than the son’s age

comparison to be done on the basis of son’s age

Hence 88/40 = 2.2
