letx=ram age
y=daughter's age
x=7y
after 5 years
x+5=5(y+5)
x+5=5y+25
7y+5=5y+25
7y-5y=25-5
2y=20
y=10
x=7y
x=7(10)=70
therefore present age is ram=70 and daughter=10
check afetr 5 years ram is 75 and daughter is 15
15x5=75

ram is 7 times old as his daughter. after 5 years he will be 5 times old as his daughter. what are their present age?

Let daughter's current age, be D
Then Ram's current age = 7D
We then get: 7D + 5 = 5(D + 5)
7D + 5 = 5D + 25
7D - 5D = 25 - 5
2D = 20
D, or daughter's current age = , or
Ram's current age: 7(10), or
