Answer 2

Answer:

Concept:

• We need to understand the statement and create the algebraic expression using the given statement.
• Consider x be the unknown value in the algebraic expression.
• Usually, one of the following four forms—addition, subtraction, multiplication, or division—should be used for the algebraic expression.
• To find the value of x, move the variable to the left and the other values to the right.
• Simplify the values to determine the result.

Given:

Number of fruits in a bag is

• All orange except $15$.
• All mangoes except $20$.
• All banana except $25$.

To find:

We need to find number of fruits in a bag.

Solution:

Let $x$ be the number of fruits in the bag.

So,

Number of Oranges $= x-15$

Number of Mangoes $= x-20$

Number of banana $=x-25$

Total number of fruits is the sum of number of oranges, number of mangoes and number of banana.

⇒  $x= (x-15) + (x-20) +(x-25)$

⇒  $x= x-15+x-20+x-25$

⇒  $x = x+x+x-(15+20+25)$

⇒  $x= 3x-60$

⇒  $x-3x=-60$

⇒  $-2x=-60$

⇒  $x = \frac{60}{2}$

⇒  $x=30$

Number of fruits in the bag is $30$.

Number of Oranges $= x-15=30-15=15$

Number of Mangoes $= x-20=30-20=10$

Number of banana $=x-25=30-25=5$

Therefore, Number of fruits in the bag is $30$.
