Answer 1

Step-by-step explanation:

Q) A boy has x coins of 50p, 2x coins of 25p, 4x coins of 10p, 8x coins of 5p. Find the no of 5p coins if the value of all coins is 9rs = 900p

According to the question,

(50x)+(25×2x)+(10×4x)+(5×8x)=900

50x+50x+40x+40x=900

180x=900

x=900/180=5

Therefore, the no of 5p coins is 8x = 8×5 = 40 coins
