Answer 1

Answer:

100

Step-by-step explanation:

Let us assume the number of notes of each currency be x.

So the ratio can be written as-

2x:3x

Since the total amount is ₹1600,

10(2x) + 20(3x) = 1600

20x + 60x =1600

80x = 1600

x = 20

The number of ₹10 notes= 2x = 2(20) = 40

The number of ₹20 notes = 3x = 3(20) = 60

The total number of notes = 60 + 40 = 100
