Answer 2

Let the ratio be "x".

1:2:3 → x : 2x : 3x

New ratios are x : 2x : 3x.

So, Number of coins of 25 paise = x

Number of coins of 10 paise = 2x

Number of coins of 5 paise = 3x

Now Total money = Rs 30

=30 × 100 paise = 3000 paise

So, 25(x) + 10(2x) + 5(3x) = 3000

→ 60x = 3000

→ x = 3000/60 = 50

So, Number of coins of 5 paise = 3x = 150
