Question

In a bag there are coins of 25p, 10p and 5p in the ratio 1:2:3.If there are rs.45 in all then find how many 25p coins are there ?

Answer 1

Answer:

75 coins

Step-by-step explanation:

Let say x is common multiplier

Then 25, 10 & 5 respectively 1x :2x:3x

So

25x + 10×2x + 5×3x = 45×100

60x = 4500

x = 75

Answer 2

$let \: the \: no. \: of \: 25p \: of \: coin = x \\ no. \: of \: 10p \: of \: coin = 2x \\ no. \: of \: 5p \: of \: coin = 3x \\ \\ we \: need \: to \: find \: the \: coins \: in \: \\ paise \: so \: we \: need \: to \: convert \: 45 \: \\ rupees \: into \: paise - - \\ \\ so \: \: 45 \times 100 = 4500 \: \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: acc. \: to \: question - - \\ 25x + (10 \times 2x) + (5 \times 3x) = 4500 \\ = > 25x + 20x + 15x = 4500 \\ = > 60x = 4500 \\ \\ = > x = \frac{4500}{60} \\ \\ = > x = 75 \\ \\ no. \: of \: coins \: of \: 25p = 75 \: coins \: \\ \\ \\ please \: mark \: as \: brainliest.$
