Answer 2

Answer:

40

Step-by-step explanation:

Given,

20p : 50p : 1rs =7:8:5

So,

20p=7x

50p=8x

1rs=5x

So,

7x+8x+5x=100

20x=100

x=5

Verification,

Amount(rs.)=5(5)*1

                  =25 Rs.

Amount(20p)=7(5)*1/5

                      =7

So,

difference=25-7

                =18

                      which is given.

So,

Number of 50p coins=8(5)

                                   =40
