In 2073 BS father's age was 7 times his daughter devyani's age. In 2081 BS father's age will be 3 times only his daughter's age.
Find the birth date year of Devyani?
1 answer:
Answer:
2069.
Step-by-step explanation:
Let Devyani's age in 2073= x years and y be her fathers age Then:
y = 7x
- and in 8 years time ( 2081) we have:
y + 8 = 3(x + 8)
y = 3x + 24 - 8
y = 3x + 16. Eliminating y from the 2 equations:
7x = 3x + 16
4x = 16
x = 4.
So in 2073 she was 4 years old
Therefore she was born in 2069.

10/3 x + 5 - 6/3 x
10/3 x - 6/3 x + 5
4/3 x + 5
the answer is
x=8y/3(1-8y)
y=3x/8(1+3x)
