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* + 5*x* + 10*x* = 480

16*x* = 480

*x* = 30.

Hence, total number of notes = 3*x* = 90.

One (rupee)+ Five(rupee) + Ten(rupee) = 16 (rupee)

Rupees 480 has to be distbted in these denomination i.e, 16

so 480/16 = 30

one rupee 30 notes

five rupee 30 notes

ten rupee 30 notes

total 90 notes.

@All.

How 16 came means;

=> x + 5x + 10x = 16x.

How 16 came means;

=> x + 5x + 10x = 16x.

@Amortya.

Let no.of 5 rupee note be X.

Then,

No.of 10 rupee note will be (70-X).

Therefore,

5X-10( 70- X) = 590,

X = 22.

Therefore num of 10 rupee note is 70-22 = 48.

Correct me, if I am wrong.

Its very simple,

Just we take some secs to think about the ques that's enough,

Exp:

After reading question just go for the given options and divide by 3 as the denominations are.

Then add all those to the sum of 480.

1. 45/3 15 so each it come 240.

2. 60.....320.

3. 75....400.

4. 90...480.
