Answers
Given:
The cost of 2 apples and 3 kiwi fruits is ₹37.
The cost of 4 apples and 5 kiwi fruits is ₹67.
Find:
Cost of 1 Apple and 1 kiwi fruit.
Solution:
Let the cost of one apple be ₹x and the cost of 1 kiwi fruit be ₹y.
Now, writing what is given in the form of 2 equations:
2x + 3y = 37. - A
4x + 5y = 67. - B
Multiplying Equation A by 2 and subtracting this with Equation B:
4x + 6y = 74
- 4x - 5y = - 67
y = 7.
Substituting y in equation A:
2x + 3(7) = 37.
2x = 37 - 21.
x = 16/2.
x = 8.
Therefore, the cost of 1 Apple is ₹8 and the cost of 1 kiwi fruit is ₹7. And the cost of 1 Apple and 1 kiwi fruit is ₹(8 + 7) = ₹15.
Answer:
Cost of 1 apple = ₹8.
Cost of 1 kiwi fruit = ₹7.
Cost of 1 Apple and 1 kiwi fruit = ₹15.
Answer:
Given :-
- A man buys 2 apples and 3 kiwi fruits for Rs 37, if he buys 4 apples and 5 kiwi fruits for Rs 67.
To Find :-
- What is the total cost of one apple and one kiwi fruit.
Solution :-
Let,
Cost of 1 apple be Rs a
Cost of 1 kiwi fruit be Rs b
Now, according to the question :
A man buys 2 apples and 3 kiwi fruits for Rs 37.
Again,
A man buys 4 apples and 5 kiwi fruits for Rs 67.
Now, by multiplying the equation no 1 by 2 we get,
Now, by subtracting the equation no 3 with equation no 2 we get,
Again, by putting b = 7 in the equation no 2 we get,
Hence,
Now, we have to find the total cost of 1 apple and 1 kiwi fruit :
The total cost of one apple and one kiwi fruit is Rs 15.
