Dunno was trained by Toropyzhka to walk faster. Before training, he walked a path of
S meters in
t1 seconds. After training Dunno's speed increased by
P%. Write a program that determines which path (in meters) Dunno will walk in
t2 seconds after training with Toropyzhka.
Input
Four integers as input:
S (1<=S<=100),
t1(1<=t
1<=100),
P (1<=P<=100)
and
t 2 (1<=t
2<=100).
Imprint
Print one number - the answer to the problem.
