Question

Viresh has 80 rs in currency notes of rs 10 and rs 5 . If the note of rs 5 currency note is one more than the noof rs 10 notes how many of each does he have

Answer 1

Answer:Let the number of 5 Rupee note = x

Then the number of 10 Rupee note = 90 - x

Total money = Rs. 500

As per the given condition,

5x + 10(90 - x) = 500

5x + 900 - 10x = 500

-5x = -400

x = 80

Hence, number of 5 Rupee note = 80

And, number of 10 Rupee note = (90 - 80)=10

Answer 2

Answer:

Let 10₹ notes = x

5₹ notes = (x+1)

A/q,

10(x)+5(x+1) = 80

10x+5x+5 = 80

15x = 75

x= 5

so

10₹ notes = x = 5

10₹ notes = x = 5 5₹ notes = (x+1) = 6
