## How many toys?

**Number Puzzle #90**

A man had Rs.900 and brought some toys with all the money. Out of which 5 toys were defected. He sold all the remaining toys by increasing the price by Rs.2 and made a profit of Rs.80.

What is the no.of initial toys and the initial cost of toys?

Check your answer, **Number of Toys**:-

Check your answer,** Initial Cost**:-

Now, we can form these two equations from these

x*y = 900;//Total cost

(y+2)(x-5) = 900+80;//as he mad profit of Rs.80 by selling x-5 toys in Rs.(y+2).

xy + 2x -5y -10= 900+80;

2x-5y = 90;

2x-5*900/x = 90

2x^2 -4500 = 90x;

x^2 -45x – 2250 = 0;

(x-75)(x+30) = 0;

x = 75 and x =–30, as number of toys cant be negative, initial **number of toys were 75**.

**Initial Cost = 900/75 = Rs.12.**

Lets consider first product of first 3 smallest integers

1*2*3 = 6

Now if we take the next smallest intege i.e. 4 then the product will become 24 thus we need to go back and consider negative numbers

thus (-2)*(-1)*1*2*3 = 12.

## If 11 + 11 = 8, 12 + 12 = 12

Three friends went to a hotel. The bill was Rs $75, Each one of them contributed $25. The waiter took the bill to the cashier. For some reason cashier was happy & decided to give them a discount of $5 and asked the waiter to return them $5.

Now the waiter was confused. How to distribute $5 among 3 persons?

He kept $2 in his pocket and gave $1 to each one of the 3 persons. So initially each one had contributed $25. Now as they are Given $1 back, their contribution reduces to $24. They all contributed $24. i.e. 24×3=72 and 2 dollors are in the waiter’s pocket.The total becomes $74. But they had paid $75.

**Where is the remaining $1?**

See Answers

Total given by customers = 3*24 = 72 = 70(with cashier) + 2 (with waiter).

in other words $75 earlier given by customer are distributed as

70(with cashier) + 2(with waiter) + 3(one dollar with each customer).
