Answer:
x = 6
y = 3
6 twenty-five paisa coin
3 fifty-paisa coins
Step-by-step explanation:
x -----> twenty-five paisa coin
y -----> fifty-paisa coins
0.25x + 0.5y = 3.00 per 100
x = 2y
25x + 50y = 300
x = 2y
25(2y) + 50y = 300
50y + 50y = 300
100y = 300
y = 300/100
y = 3
x = 2y
x = 2(3)
x = 6
Answer:
acceleration=final velocity - initial velocity/total time

a=65-35/5
a=30/5
a=6

This is very similar to the last question:-
0.51No = No e^_0.0001t
t = ln 0.51 / 0.0001
