Answer
Given,
- Sum of rupees got from 5 and 10 rupees note = 500
- Total numbers of notes = 90
To find,
- Note of each type
Solution ,
Let the number of 5 rupees note be 'x'
Let the number of 5 rupees note be 'x' Let the number of 10 rupees note be 'y'
According to the question :
⇛ 5(x) + 10(y) = 500
Dividing the equation by 5 we get,
⇛ x + 2y = 100 ----------(1)
Also,
⇛ x + y = 90 -----------(2)
Subtracting (2) from (1) we get ,
⇛ y = 10
Putting y = 10 in (2) we get,
⇛ x = 80
Hence number of 5 rupees note wilk be 80 and number of 10 rupees note will be 10
