Age Word Problem

Let Sania's current age be $S$ and Yogesh's current age be $Y$. From the first statement: The sum of ages of Sania and Yogesh is 50 years. $S + Y = 50$ (Equation 1) From the second statement: Sania is twice as old as Yogesh was 5 years ago. Yogesh's age 5 years ago was $Y - 5$. So, $S = 2(Y - 5)$ (Equation 2) Now we solve the system of equations: From Equation 2: $S = 2Y - 10$ Substitute this expression for $S$ into Equation 1: $(2Y - 10) + Y = 50$ $3Y - 10 = 50$ $3Y = 60$ $Y = 20$ Now find Sania's age using Equation 1: $S + 20 = 50$ $S = 30$ So, Sania's present age is 30 years.
