notes as she has 50 rupees notes altogather she
has 2700 rupees. How many 50 rupees notes she
have a​

Answer 1

Answer:

let the no. of 50 rupees notes is equal to x

therefore the no. of 20 rupees notes will be 2x

the total money is 2700 rupees

so

50*x + 2*20*x = 2700

50*x + 40*x = 2700

90*x = 2700

x = 2700/90

x = 30

so the number of 50 rupees notes is 30
