Answer:
52
Step-by-step explanation:
Let there be 2x, 4x, 5x coins of 1 rupee, 2 rupee and 5 rupee respectively.
2x × (1) + 4x × (2) + 5x × (5) = 455
2x + 8x + 25x = 455
35x = 455
x = 13
Number of 2 coins = 4 × 13
= 52

A purse contains 50p and RS 1 in the ratio
3 :2 the total amount in the purse is RS 70 find the number of 50p and Rs 1 coins.
- No.of coins of 50 paise and
- No.of coins of 1rs coins.
- No. of 50paiae coins=60pcs.
- No.of 1 rs coins=40 rs.
______________________________________________
- let the number of 50paise coins =3x
- and the number of rs 1 coins =2x
- where....x>0
now ....
the total amount in the purse is RS 70.
- 3x(50)+2x(100)=7000
- =>350x=7000
- =>X=7000/350=20
therefore the number of 50paise coins is 3(20)=60pcs
and the number of 1rs coins is =2(20)=40pcs
