Question

Nisha has ₹100. She spends one fourth of the money on notebook and buys five pens worth ₹10 from the remaining amount. How many rupees are left with her?

Answer 1

Step-by-step explanation:

1/4 of Rs.100 = Rs.25

Remaining amount after buying notebook = Rs.100 - Rs.25

= Rs.75

After buying pens = Rs.75 - 50 = Rs.25

Answer 2

$\huge\mathfrak\blue{Answer:}$

Given:

• We have been given that Nisha has Rs.100 she spent 1/4 of the money on notebook
• She then buy 5 pens worth Rs.10

To Find:

• We have to find the amount of money left with Nisha

Solution:

Given that Money Owned by Nisha

$\boxed{\sf{Initially \: money = Rs.100}}$

Nisha then spent one fourth of the money in buying a notebook

$\boxed{\sf{Notebook \: Price= \dfrac{1}{4} \times Initial \: Money}}$

Money spent on buying notebook is :

$\mapsto \sf{S_1= \dfrac{1}{4} \times 100}$

$\mapsto \sf{S_1= \dfrac{100}{4}}$

$\mapsto \boxed{\sf{S_1= Rs.25}}$

$\sf{ }$

Nisha then spent the money for buying 5 pens worth Rs.10

$\boxed{\sf{Cost \: of \: One \: Pen = Rs.10}}$

Money spent on buying pens is :

$\mapsto \sf{S_2 = Number \: of \: Pen \times Price }$

$\mapsto \sf{S_2 = 5 \times 10 }$

$\mapsto \boxed{\sf{S_2 = Rs. 50 }}$

$\sf{ }$

Total money spent in pen & notebook is :

$\mapsto \sf{Total \: Money \: Spent = S_1 + S_2}$

$\mapsto \sf{25 + 50}$

$\mapsto \sf{75}$

$\boxed{\sf{Total \: Money \: Spent =Rs.75} }$

________________________________

Money left with Nisha is :

$\implies \sf{Initial \: money - Money \: Spent }$

$\implies \sf{100 - 75 }$

$\implies \sf{Rs.25 }$

Money left with Nisha is Rs.25
