Answer 1

Answer:

Let the number of 50p coin be x and 25p be y

According to question,

x+y=40 (i) and

25x+50y=1250 (ii)

Multipling equation (i) by 25 we get,

25x+25y=1000 (iii)

Subtracting (iii) from (ii) we get,

25x+50y=1250

25x+25y=1000

25y=250

=>y=

25

250)

=>y=10

Putting the value of y in equation (i) we get,

x+y=40

=>x=40−10

=>x=30

∴x=30(25 paisa coins)

y=10(50 paisa coins
