A man has Rs.480 in the denominations of one-rupee notes, five-rupee notes and ten-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has ?
Answer: Option
Explanation:
Let number of notes of each denomination be x.
Then x + 5x + 10x = 480
16x = 480
x = 30.
Hence, total number of notes = 3x = 90.

1 rupees notes 90 = 1*90 = 90.
5 rupees notes 90 = 5*90 = 450.
10 rupees notes 90 = 10*90 = 900.
= 90+450+900/3.
= 1440/3 = 480.
No of notes 90.
5 rupees notes 90 = 5*90 = 450.
10 rupees notes 90 = 10*90 = 900.
= 90+450+900/3.
= 1440/3 = 480.
No of notes 90.

Denomination same and it is 3.
So 1+5+10 = 16.
So [480/16]x3 = 90. Its simple.
So 1+5+10 = 16.
So [480/16]x3 = 90. Its simple.

Divide the notes 30*10 = 300.
30*5 = 150.
30*1 = 30.
Add = 300+150+30 = 480.
No of notes = 90.
30*5 = 150.
30*1 = 30.
Add = 300+150+30 = 480.
No of notes = 90.
