Question

Six apples and one pear cost $1.07. At the same price, three apples and six pears cost $1.47. An apple costs

Answer 1

Answer: $\ 0.15$

Step-by-step explanation:

Given

Six apples and one pear cost $\ 1.07$

Also, three apples and six pears costs $\ 1.47$

Suppose $x$ and $y$ be the price of apple and pear. So, we can write the cost as

$\Rightarrow 6x+y=1.07\quad \ldots(i)\\\Rightarrow 3x+6y=1.47\quad \ldots(ii)\\\text{solve (i) and (ii) we get}$

$x=0.15,\ y=0.17$

The cost of an apple is $\ 0.15$
