The best answer, in my opinion, is ¨you don´t indulge in impulse buying¨
First we have to change rupees into paise .
[Rupees = 100paise]
Sandwiches = 1.85+1.85=370paise
Drinks = 72p+72p=144paise
Sweets = 105paise
Adding the total payment:-
370+144+105=619paise
619 paise means 6.19rupess
Hence 10-6.19=3.81rupess.
Answer:
806 million years
Step-by-step explanation:
From the information given:
Firstly, we need to determine the no. of ways we can choose n many words in the dictionary & array them in
ways.
Thus, the no. of unique books possible of length till K is:

where K = 6, we have the value to be:
= 25420530373932821216635722990977
Thus, the time required to write all possible texts of 6 is:
= (25420530373932821216635722990977)/10⁶
≅ 806 million years.
