120% of x is equal to 78.

Degger [83]

Answer:

A. 1.2x = 78

B. x = 65

Step-by-step explanation:

Just informally, first:

x is the number that we don't know. 120% of that number is a number BIGGER than that number. 120% of x is 78. So 78 is BIGGER than the number that we don't know.

120% of x = 78

Change 120% to a decimal by moving the decimal two places to the left. Multiply.

1.2x = 78

To solve, divide both sides by 1.2

x = 78/1.2

x = 65

Answer:

<h2>Option B:</h2><h3>112 families </h3>

Step-by-step explanation:

Given,

No. of families = 75

Out of 75 no. of families had cars = 42

Out of 1, no. of families can have cars

$= \frac{42}{75}$

Therefore, 

Out of 200 families, no. of families had cars

$= 200 \times \frac{42}{75}$

$=200 \times \frac{14}{25}$

= 8 × 14

= 112

Hence, 

option B is correct as 112 families have cars out of 200 families (Ans)
