Question

a bag contains a sum of ₹777 in the form of ₹1,₹2 and ₹5 coins in the ratio 7:5:4. find the number of each type of coin​

Answer 1

Step-by-step explanation:

let the coins be

1 ruppee coin = 7x

2ruppee coin= 5x

5 ruppee coin = 4x

so total money = 777 ruppees

hence , (7x)*1+(5x)*2 +(4x)5 = 777

(7+10+20)x = 777

x= 777/37

no. of one ruppee coins are 7*777/37

no. of two ruppee coins are 5*777/37

no. of 5 ruppee coins are 4*777/37
