Question

i) A shopkeeper sells apples and oranges in his shop. The number of apples is 20 more than two-third
number of oranges. Find the number of oranges, if there are 70 apples.​

Answer 1

Step-by-step explanation:

oranges =20+2/3=60+2/3=62/3

apples =70

=70-62/3

=210-62/3

=148/3

Answer 2

Given: Number of apples is 20 more than two-third number of oranges.

           Number of apples = 70

To find: Number of oranges

Let: Number of oranges be $x$

Solution: Given that,

Number of apples = 70

also, number of apples is 20 more than two-third number of oranges.

i.e., number of apples = $\frac{2}{3} x + 20$

⇒ $\frac{2}{3} x + 20 = 70$

⇒ $\frac{2}{3}x = 70 - 20$

⇒ $\frac{2}{3} x = 50$

⇒ $x = 50 * \frac{3}{2} = 75$

Hence, there are 75 oranges.
