Question

5 years ago, the age of Parvati was 4 times the age of her son. The sum of their present ages is 55 years. Find Parvati's present age ​

Answer 1

5 years ago

let age of son = x

age of Parvati = 4x

At present

age of son = x+5

age of Parvati = 4x+5

Their sum = 55

x+5+4x+5 = 55

5x +10 =55

5x = 45

x = 9

Parvati's age 5 years ago= 9*4 = 36

Parvati's present age = 41

Answer 2

Answer:parvati's age= 41 years

His son's age = 14 years

Step-by-step explanation:let son's age be x years and parvati's age be y years

5 years ago:

4 (x-5)=y-5

4x-20=y-5

4x-y=15...........eq.1

Present age's sum:

X+y=55...... eq.2

From eq.1 and2

5x=70

X= 14

Thus y=41......

Hope it helps you...
