HELLO DEAR !!!!....


________________________


LET the number of 25 paisa coins be x and 50 paisa coins be y

so , 25x +50y = 1250 - - - - (1) ( convering values in paisa)

and x +y = 40. - - - - - (2)

so x = 40 - y 


PUTTING the value of x in equation (1)

so, 25(40 - y) + 50y = 1250

1000 - 25y + 50y = 1250

25y = 1250 -1000

25y = 250

y = 10


SO the number of coins 50 paisa is 10 now putting this value of y in eq (2)

x + y = 40

x + 10= 40

and x =30


So , 25 paise coins = (x) = 30

50 paise coins = (y) = 10
