(d) 37​

Answer 1

Answer:

THE ANSWER IS:-

OPTION (B) 45

Step-by-step explanation:

LET THE AGE OF SON BE x

SO,

AGE OF FATHER = 3x

AFTER 5 YEARS,

FATHER'S AGE = (3x+5)

SON'S AGE = (x+5)

SO,

A.T.Q.,

(3x+5) = 5/2(x+5)

3x+5 = (5x+25)/2

2(3x+5) = (5x+25)

6x+10=5x+25

6x-5x = 25-10

x = 15

SO,

AGE OF FATHER = 3x = 3*15=45 YEARS

SO,

OPTION (B) IS CORRECT
