Question

What is aman present age after 20 years the age 10 times of 10 years back?

Answer 1

Answer:

Step-by-step explanation:  the question is wrong as it hasnt given the base value , so if u get to know the base value put it in place of y

let aman present age be = x years

according to your dynamic question ....

10(x-10) + 20 =y

100x -100+20= y

100x - 80  = y

x = (y+80)/100
