If all the money in the piggy bank adds upto rupees 555 find the number of rupees 10 coins in it​

Answer 1

Answer:

48

Step-by-step explanation:

No. of Rs. 1 coins = X

No. of Rs. 2 coins = 2X

No. of Rs. 5 coins = 4X

No. of Rs. 10 coins = 16X

ATQ,

Total amount in piggy bank = 555

Total amount of Rs. 1 coins = X*1 = X

Total amount of Rs. 2 coins = 2X*2 = 4X

Total amount of Rs. 5 coins = 4X*5 = 20X

Total amount of Rs. 1 coins = 16X*10 = 160X

Now,

X + 4X + 20X + 160X = 555

185X = 555

X = 3

No. of Rs. 10 coins = 16X = 16*3 = 48
