Mary went up the Old Tower taking 3 steps per second. Then she carefully came down from the tower taking 2 steps per second. It took Mary 25 seconds longer to come down than to go up. How many steps does the Old Tower have?

let the number of steps=x

time taken to go up=1/3×x=x/3 s

time taken to go down =1/2×x=x/2 s

now we do,

x/2-x/3=25

finally we multiply by 6,

3x-2x = 25 x 6

x=150

hope this helps
