Question

Tanya age will be 4 times her present age after 15 years. How old is she now?​

Answer 1

Step-by-step explanation:

$\huge\underline\yellow{\sf Answer :-}$

• Let Tanya's present age = X years
• 4 times her present age= 4*x = 4x years.

______________

$\large\implies{\sf }$ After 15 years her ( Tanya's) age will be ( x + 15) years.

According to the question : x + 15 =4x

$\large\implies{\sf }$15 = 4x - x

$\large\implies{\sf }$15=3x

$\large\implies{\sf }$ $\large{\sf {\frac{15}{3x}}}$

$\large\implies{\sf }$ x= 5=X

• So, Tanya is 5 years old now.

Answer 2

Tanya present age = x

4 times of her present age is = 4×x = 4x

15 + x = 4x

15 = 4x - x

15 = 3x

x = 15/3

x = 5

hence present age of Tanya is 5 years
