Find two consecutive even numbers such that the difference of one-half the larger and two-fifths the smaller is equal to 38

expeople1 [14]

EXPLANATION

The consecutive even numbers are
$370 \: and \: 372$

EXPLANATION

Let
$x$
be the first even number then, the next even number will be,

$x + 2$

The difference of one-half the larger one and two-fifth the smaller one is 38 gives the equation,

$\frac{1}{2} (x + 2) - \frac{2}{5} x = 38$

We multiply through with an LCM of 10 to get,

$10 \times \frac{1}{2} (x + 2) - 10 \times \frac{2}{5} x = 38 \times 10$

This simplifies to,

$5(x + 2) - 4x = 380$

We expand the brackets to get,

$5x + 10 - 4x = 380$

We group like terms to get,

$5x - 4x = 380 - 10$

This simplifies to
$x = 370$

Therefore the next even number is is
$372$

The price of a computer was decreased by 20% to £136. What was the price before the decrease?

Contact [7]

Answer:

£ 170 .

Step by step explanation :

Given that the price of a computer was decreased by 20% to £136. And we need to find the Original price before the decrease. So , let the earlier price be x ,

Decrease in 20 % :-

⇒ Decreased price = 20% of x

⇒ Decreased price = 20/100 × x

⇒ Decreased price = x/5

New price :-

⇒ New price = x - x/5

⇒ New price = 5x - x/5

⇒ New price = 4x/5.

But its given £ 136 , So

⇒ 4x/5 = £ 136

⇒ x = £ 136 * 5/4

⇒ x = £ 170

<h3>Hence the Original price was £ 170 .</h3>
