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, Initial Cost:-Click here to See Solution
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.

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?
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).
