Question

For your birthday, you plan to distribute one choclate each to the $30$ children of an orphanage and a sweet each to the $23$ people of a senior citizen home. Each chocolate costs $₹15$ and cost per sweet is $₹8$. Your mother gives you $₹800$. In the shop, you realise that one $₹100$ note is lost. So, after purchasing chocolates and sweets, how much money will be left with you?

Answer 1

Step $1$: Finding the money needed to purchase chocolates and sweets:

For birthday party, i require $30$ chocolates and $23$ sweets, so

Cost of $1$ chocolate is $₹15$

Cost of $30$ chocolates is $₹15\times 30=₹450$

Cost of $1$ sweet is $₹8$

Cost of $23$ sweets is $₹8\times 23=₹184$

Total cost of $30$ chocolates and $23$ sweets is $₹450+₹184=₹634$

Hence, the total cost of $30$ chocolates and $23$ sweets is $₹634$

Hence, the money needed to purchase $30$ chocolates and $23$ sweets is $₹634$

Step $2$: Finding the money left:

Lost money is $₹100$

So, Money Left is $\text{=Total money-(Money needed for purchasing+Money lost)}$

Hence, the left money is $800-(634+100)=800-734=₹66$
