Answer:

Hello,There! I'll be glad to help!

<h2>Question</h2>

what is 4/2/3 x 1/3/7 ?

<h2>Answer</h2>

$6\frac{2}{21}$

Step-by-step explanation:

Rewriting our equation with parts separated

$4 +\frac{2}{3} + 1 +\frac{3}{7}$

Solving the whole number parts

$4 + 1 =5$

Solving the fraction parts

$\frac{2}{3}+\frac{3}{7} =?$

Find the LCD of 2/3 and 3/7 and rewrite to solve with the equivalent fractions.

LCD = 21

$\frac{14}{21} +\frac{9}{21} =\frac{23}{21}$

Simplifying the fraction part, 23/21,

$\frac{23}{21} =1\frac{2}{21}$

Combining the whole and fraction parts

$5 + 1+ \frac{2}{21} =6\frac{2}{21}$

Hence, The answer is $6\frac{2}{21}$

Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given as follows:

Josephine: 1/9.

Assistant: 1/x.

Together: 1/7.

Hence:

$\frac{1}{9} + \frac{1}{x} = \frac{1}{7}$

$\frac{x + 9}{9x} = \frac{1}{7}$

$9x = 7x + 63$

2x = 63

x = 31.5.

It would take the assistant 31 hours and 30 minutes to do it alone.

Answer:

The correct answer is - A)8% B) 3%

Step-by-step explanation:

A) Let assume:

the cost price of the goods - $y.

the selling price of the goods - $x.

Given: The retailer sold at 4% discount, or 0.96x (100% - 4% = 96%). Since the goods were sold to make 20% profit, therefore it was sold for:

1.2y (100% + 20% = 120%).

Solution:

The refrigerator was sold at 13% VAT at Rs. 10848:

then,

=> 1.2y + 13%(1.2y) = 10848

=> 1.2y + 0.156y = 10848

=> 1.356y = 10848

=> y = 8000

Thus, the cp is Rs 8000.

The selling price is:

=> 0.96x = 1.2y

=> 0.96x = 1.2(8000)

=> x = 10000

The sp is Rs. 10000

For a profit of 15%, that is 1.15(8000) = 9200, the discount is:

(1 - discount)10000 = 9200

1 - discount = 0.92

Discount = 1 - 0.92 = 0.08 or 8%

B) Let C & M as cost price & marked price of the scanner machine respectively.

(1 + 20/100)*C = 41400

or (6/5)*C = 41400

or C = (5/6)*41400

= 34500 (Rs)

(1 - 10/100)*(1 + 15/100)*M = 41400

or (9/10)*(23/20)*M = 41400

or M = (10/9)*(20/23)*41400

= 40000 (Rs)

Let R% as the reduction in the percent in discount

(1 - 10/100 + R/100)*(1 + 15/100)*M

= (1 + 20/100 + 4/100)*C

or (9/10 + R/100)*(23/20)*40000

= (31/25)*34500

or 9/10 + R/100

= (20/23)(31/25)*(345/400)

or R/100 = 0.93 - 0.9 = 0.03

or R = 3%
