Question: The cost of 16 packets of salt, each weighing 900 grams is 28. What will be the cost of 27 packets, if each packet weighs 1 kg?
- 52.5
- 56
- 58.5
- 64.75
- 65
Correct Answer: A
Solution and Explanation
Approach Solution 1:
There is only one approach to solve the problem.
Given:
- There are 16 packets of salt
- Each packets weigh 900 grams
- The cost of these 16 packets is 28.
Condition:
- If each packet weighs 1 kg
Find out:
- What will be the cost of 27 packets
The cost of 16 packets of salt, each weighing 900 grams is 28.
=> So cost is16*900g = 28.
Let us find the weight of 1 gram
The weight is :
28/16*900—---------------- 1
Now, we need to find out the cost of 27 packets, if each packet weighs 1 kg,
The equation becomes = 27*1000g (since 1kg=1000 grams)----------2
Now considering equation 1 and 2, we get:
(28/16*900) * 27000
= 7*30/ 4
=52.5
