Answer:
8. Given - Manu paid rupees 602.50 for 10 books
To find - How much extra money is to paid for buying 3 more books, that is, the cost of 3 books
Solution: If the cost of 10 books is 602.50, then the cost of 1 book is:
602.5
---------
10
= 60.25
If the cost of one book is 60.25 rupees, then the cost of three books is:
60.25 x 3
= 180.75
Therefore, to buy 3 more books, she has to pay an extra amount of rupees 180.75 .
9. If the price of 1.25 kg of potatoes is 20 rupees, then the cost of 2.75 kg potatoes is,
20/1.25 = x/1.25
20x2.75 / 1.25 = x
55/ 1.25 = x
44 = x
So the cost of 2.75 kg potatoes is 44.
If she gives the vendor 100 rupees, then the change returned will be,
100 - 44 = 66 rupees.
10. If the product of two numbers is 25.955 and one of the number is 2.9, then, taking the other number as y,
2.9 × y = 25.955
y = 25.955 / 2.9
y = 8.95
The other number is 8.95.
