many grapes, kiwi &
strawberry will you buy ?
Answers
For Rs. 100, we can buy 80 grapes, 1 Kiwi and 19 strawberries
Step-by-step explanation:
After analyzing the problem, we note that if we buy 40 grapes, we have to buy 60 other fruits.
However, any combination of 60 kiwi and strawberries cost more than Rs. 99.
Hence, we need to buy more than 40 grapes. Furthermore, we cannot use fractions of the cost. So, the next whole integer that we can buy for is Rs. 2, i.e., we need to buy 80.
Hence 2 x 40 = 80 grapes.
That leaves 20 fruits
We can buy 1 Kiwi for Rs 3.
Thus, 19 strawberries can be bought for = 19 x 5 = 95
Thus, we can buy 80 grapes + 1 Kiwi + 19 strawberries for
Rs 2 + Rs 3 + Rs 95 = Rs 100
Step-by-step explanation:
Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of force. By resolving force →F into two components : (i) F cosθ in the direction of displacement of the body. (ii) F sinθ in the perpendicular direction of displacement of the body.
