Correct Answer - Option 1 : Rs. 15
Given
A man buys 2 apples and 3 kiwi = Rs.37
He buys 4 apples and 5 Kiwi for Rs.67
Concept used
We solve these type of question by equation method
Calculation
Let the price of 1 apple be Rs.x
Let the price of 1 Kiwi be Rs.y
According to question
∴ Price of 2 apples and 3 kiwi
⇒ 2x + 3y = Rs.37 ----(1)
⇒ Price of 4 Apples and 5 Kiwi
⇒ 4x + 5y = Rs.67 ----(2)
⇒ Multiply equation (1) by 2 and then subtract it from equation (2), we get
⇒ y = Rs.7
⇒ put the value of y in equation (1), we get
⇒ 2x = 37- 21
⇒ x = Rs.8
∴ price of 1 apple and 1 kiwi
⇒ 8 + 7
⇒ Rs.15
