A). 9080 paise
B). 90 Rs. 8 p
C). 90 Rs. 18 p
D). 90 Rs. 80 p

Answer 1

Hint: In this question we have to find the cost of 2 ice creams and the cost of 1 ice cream cone is given. So, first we will convert the cost given in Rs. in paise and then we will add 40 paise in it. This will be the cost of 1 ice cream so, we will multiply it by 2 to find the cost of 2 ice creams.

Complete step-by-step solution:
Given: cost of 1 ice cream cone is 45 Rs. and 40 paise.
We will convert the cost in Rs. to paise. 1 rupee is equal to 100 paise. So, cost of 45 rupees will be:
$ = 45 \times 100$
$ = 4500paise$
The cost of 1 ice cream cone in paise $ = 4500 + 40$
$ = 4540paise$
To find the cost of 2 ice creams, we will multiply the cost of 1 ice cream with 2.
$ = 4540 \times 2$
$ = 9080paise$
The cost of 2 ice creams in paise is 9080 p.
Now, we will find the cost of 2 ice creams in Rs. To convert paise in rupees we have to divide the amount in paise by 100.
Cost of 2 ice creams in Rs. $ = \dfrac{{9080}}{{100}}$
$ = 90.80$
$ = 90Rs.80p$
The cost of 2 ice creams in Rs. is 90 Rs. 80 p.
So, option (1) and option (4) are the correct answers.

Note: We know that 1 rupee = 100 paise. When we convert rupees into paise, we multiply by 100. To convert paise into rupees, we divide it by 100. We will simply put a dot (.) before the second digit from the right to convert the paise. And the digit after the point is in paise.
