4.
Browsing rates in an internet centre is Rs. 15 per hour. Nila works on the internet for 2 hours in a day for 5 days in a week. How much does she pay?
5.
Ferozkhan collects Rs.1150 at the rate of Rs.25 per head from his classmates on account of the 'Flag Day' in his school and returns Rs.8 to each one of them, as instructed by his teacher. Find the amount handed over by him to his teacher.
1.
Years in AD(CE) are taken as positive integers and BC(BCE) as negative integers.
Therefore, the difference is
= 1687 – (–323)
= 1687 + 323 = 2010 years
2.
Consider, (–81) x [5 x (–2)],(–81) x [5 x (–2)] = (–81) x (–10) = 810
Consider, [(–81) x [5 x (–2),[(–81) x 5] x (–2) = (–405) x (–2) = 810
Therefore, (–81) x [5 x (–2)] and [(–81) x 5] x (–2) are equal.
It is associative.
3.
Consider, (–42) x (–7), (–42) x (–7) = +294
Consider, (–7) x (–42), (–7) x (–42) = +294
Therefore, (–42) x (–7) and (–7) x (–42) are equal.
It is commutative.
4.
Number of hours spent on an internet for a day = 2 hrs
Therefore, number of hours spent on the internet for 5 days = 5 x 2 = 10 hrs
Cost of browsing per hour = Rs. 15
Cost of browsing for 10 hours = 15 x 10
Therefore, the amount paid by Nila for 5 days = Rs. 150
5.
Ferozkhan collects Rs.1150 at the rate of Rs.25 per head from his classmates on account of the 'Flag Day'
Total amount collected = Rs.1150
Amount per head = Rs.25
Number of students = 1150 ÷ 25 = 46
Amount returned to each student is Rs.8
Amount returned to 46 students = 46 x 8 = Rs.368
Amount handed over to the class teacher = Rs.1150
