Answer 2

Given - Total notes and value of those notes

Find - Number of Rs. 50 and Rs. 10 notes

Solution - Number of Rupees 50 and Rupees 10 notes is 10 and 9.

Let the number of Rupees 10 notes be x. So, Rupees 50 notes will be (x-1).

Now, expressing the given information in equational form-

10x + 50(x-1) = 550

10x + 50x - 50 = 550

60x = 600

x = 10

So, number of Rupees 10 notes = x

Number of Rupees 10 notes = 10

Number of Rupees 50 notes = x-1

Number of Rupees 50 notes = 10-1

Number of Rupees 50 notes = 9

So, number of Rupees 50 and Rupees 10 notes is 10 and 9.
