Question

Today X is thrice as old as Y. After 13 years X will be one less than twice as old as Y will be then. Find present age of X​

Answer 1

Answer:

From given data ,

X = 3y (1)

X + 13 = (Y + 13 ) 2 - 1

On substituting the values

3Y + 13 = 2Y + 26 - 1

3y -2Y = 25 - 13

Y = 12 in 1

X = 36
