#2 - Hard Math Question

A generous owner of a company decided to give a bonus of $45 to every man and $60 to every woman on his birthday. But only one ninth of the men and one twelfth of woman were present to take the bonus.

Can you calculate the amount of money the owner spent if there were 3552 employees ?

Hard Math Question

17,760

Let us assume that there are x male employees.
No. of female employees will be (3553 – x)
One ninth of men = x/9 who received $45
And one twelfth of the women = (3553 – x) /12 who received $60

Thus total received = (45 * (x / 9)) + (60 * (3552 - x) / 12)
= 5 * 3552
= $17,760

#3 - Interesting Maths Puzzle

A women walks into a bank to cash out her check.
By mistake the bank teller gives her rupee amount in change, and her paise amount in rupees.
On the way home she spends 5 paise, and then suddenly she notices that she has twice the amount of her check.

How much was her check amount ?

Interesting Maths Puzzle

The check was for Rupees 31.63.
The bank teller gave her Rupees 63.31
She spent .05, and then she had Rupees 63.26, which is twice the check.

Let x be the rupees of the check, and y be the paise.

The check was for 100x + y paise
He was given 100y + x paise

Also
100y + x - 5 = 2(100x + y)
Expanding this out and rearranging, we find:
98y = 199x + 5

or 199x ≡ -5 (mod 98)
or 98*2*x + 3x ≡ -5 (mod 98)
3x ≡ -5 ≡ 93 (mod 98)
this quickly leads to x = 31

I saw a Jeans for Rs97. I dont have enough money , so i borrowed Rs50 from my mom and 50 from my dad = Rs100.
I bought the jeans, and had Rs3 change. I gave dad Rs1 and my mom Rs1 and kept the other Rs1 for myself. Now I owe my mum Rs49 and my dad Rs49. 49+49 = 98 + my Rs1 = 99. Where is the missing Rs1?

#8 - Tricky Math Logic Problem

A girl was fond of collecting rare stamps. When she was twenty years old, she bought a box to collect her stamps. On her every birthday, she put 250 stamps in it and her sister who was also fond of collecting stamps took out 50 stamps from it on her birthday. The girl met an accident when she was 60 years old. When her box was opened, there were only 500 stamps in it.

How is it possible logically?

Tricky Math Logic Problem

The girl was born on 29 February, thus she put 250 stamps every four years.
In forty years, she put stamps only 10 times which makes the total of 2500 stamps.
Her sister was born on any other day and she took out 50 stamps from the box forty times which makes the total stamp she took out to be 2000.

Thus after forty years, the girls box had only 500 stamps.

#9 - Christmas Beggar Maths Puzzle

On Christmas , A beggar earns 71 rupees in form of 20-paisa and 25-paisa.
He collects total of 324 coins.

Can you tell me how many number of 20-paisa and 25-paisa he got ?

Christmas Beggar Maths Puzzle

20 paisa coins : 200
25 paisa coins : 124

Explanation:
Say he collect 20-paisa coins be A
Say he collect 25-paisa coins be B
=>number of 25-paisa coins = (324 - A).

Therefore,
0.20 X A + 0.25 (324 - A) = 71
=>20A + 25 (324 - A) = 7100
=>5A = 1000
=>A = 200.

Hence, number of 25-paisa coins = (324 - A) - 124.
