A man has equal number of five, ten and twenty rupee notes amounting t...
Given:
Number of Five rupee note = Number of Ten rupee note = Number of Twenty rupee note
Calculation:
Let the equal number of five, ten and twenty rupee notes be x
⇒ 5x + 10x + 20x = 385
⇒ 35x = 385
⇒ x = 385/35 = 11
Total number of notes = 11 notes of Rs 5 + 11 notes of Rs 10 + 11 Rs of 20 =  33 notes
Check:
11 notes of Rs 5 + 11 notes of Rs 10 + 11 Rs of 20 = 11 × 5 + 11 × 10 + 11 × 20 = 55 + 110 + 220 = Rs. 385
Total number of notes = 11 × 3 = 33 
Therefore the correct answer is 33.
Alternate Method:
Since the number of Rs 5, Rs 10, and Rs 20 notes are equal, the ratio of the number of notes is = 1 ∶ 1 ∶ 1
Or, we can say, the total number of notes must be multiple of 3.
 Only two options are multiple of 3, others can be eliminated.
option 2 : 33. That means the number of notes of each dimension is 33/3 = 11.
5 × 11 + 11 × 10 + 11 × 20 = 385
∴ The total number of notes is 33.

A man has equal number of five, ten and twenty rupee notes amounting t...
Given:
- The man has an equal number of five, ten, and twenty rupee notes.
- The total amount of money in these notes is Rs. 385.

To Find:
- The total number of notes.

Solution:
Let's assume that the man has 'x' number of notes of each denomination (five, ten, and twenty rupee notes).

Step 1: Calculate the Total Amount:
The total amount of money can be calculated by multiplying the number of notes of each denomination by their respective values:

Total amount = (5 * x) + (10 * x) + (20 * x)
385 = 35x

Step 2: Solve for 'x':
Dividing both sides of the equation by 35:
x = 385/35
x = 11

Step 3: Calculate the Total Number of Notes:
Since 'x' represents the number of notes of each denomination, the total number of notes is obtained by multiplying 'x' by the number of denominations:

Total number of notes = 3 * x
Total number of notes = 3 * 11
Total number of notes = 33

Answer:
Therefore, the total number of notes the man has is 33, which corresponds to option 'B'.

Similar ACT Doubts

Adapted fromWhat I Think and Feel at Twenty-Five(1922) by F. Scott FitzgeraldAs a man grows older it stands to reason that his vulnerability increases. Three years ago, for instance, I could be hurt in only one way—through myself. If my best friend’s wife had her hair torn off by an electric washing-machine, I was grieved, of course. I would make my friend a long speech full of “old mans,” and finish up with a paragraph from Washington’s Farewell Address; but when I’d finished I could go to a good restaurant and enjoy my dinner as usual. In fact I was pretty much invulnerable. I put up a conventional wail whenever a ship was sunk or a train got wrecked; but I don’t suppose, if the whole city of Chicago had been wiped out, I’d have lost a night’s sleep over it—unless something led me to believe that St. Paul was the next city on the list. Even then I could have moved my luggage over to Minneapolis and rested pretty comfortably all night.But that was three years ago when I was still a young man. I was only twenty-two. Now, I’m vulnerable. I’m vulnerable in every way. I used to have about ten square feet of skin vulnerable to chills and fevers. Now I have about twenty. I have not personally enlarged, the twenty feet includes the skin of my family, but I might as well have, because if a chill or fever strikes any bit of that twenty feet of skin I begin to shiver. And so I ooze gently into middle-age; for the true middle-age is not the acquirement of years, but the acquirement of a family. The incomes of the childless have wonderful elasticity. Two people require a room and a bath; a couple with child requires the millionaire’s suite on the sunny side of the hotel. And yet I think that marriage is the most satisfactory institution we have. I’m simply stating my belief that when Life has used us for its purposes it takes away all our attractive qualities and gives us, instead, ponderous but shallow convictions of our own wisdom and “experience.” The older I grow the more I get so I don’t know anything. If I had been asked to do this article about five years ago it might have been worth reading.Q. From the context of the whole passage, what can be inferred about the author’s opinions on the “wisdom and experience” of middle-age?
