Answer: Leo is 24 years old,

Step-by-step explanation:

Let 'x' denotes the age of Mark.

Given ,  Leo is three times older than Mark.

i.e. Expression for Leo's age = 3x

Since , sum of their age is 32, then

x+3x=32\\\\\Rightarrow\ 4x=32

Now , divide both sides by 4 to get the value of x.

x=\dfrac{32}{4}\Rightarrow x=8

Thus , Age of Mark =  8 years

Age of Leo = 3 (8) = 24 years

Therefore , Leo is 24 years old.

The ratio of the profit, material cost and production labour of an article is 5:7:13.
IRINA_888 [86]

Answer:

The cost of producing the article is -3500 (Negative cost)

Step-by-step explanation:

The given parameters are

The ratio of the profit to material cost to production labor = 5:7:13

The amount of the material cost = 840 + Labor cost

Let the total cost = X

Therefore, we have;

The fraction of the total cost that is material cost = 7/(5 + 7 + 13) = 7/25

Therefore, the material cost = 7/25 × X

The fraction of the total cost that is labor cost = 13/(5 + 7 + 13) = 13/25

Therefore, the labor cost = 13/25 × X

However, the amount of the material cost = 840 + Labor cost, which gives;

7/25 × X = 13/25 × X + 840

7/25 × X - 13/25 × X = 840

-6/25 × X= 840

X = 840/(-6/25) = 840×(-25/6) = -3500

The cost of producing the article = -3500.

Anvisha [2.4K]

If you consume less energy you pay less with respect to the amount of energy you saved. If you saved 16% of total energy you should expect to lower your bill by 16%. Count how much is left -> 1900-1900*0.16=1596$
