D) A shopkeeper bought two radios for Rs 6,000. He sold one of them at a profit of 20℅

Orlov [11]

Answer:

2400 and 3600

Step-by-step explanation:

Radio 1 cost = x

Radio 2 cost= 6000- x

x*1.2+(6000-x)*0.9= 6000*1.02
1.2x-0.9x+5400=6120
0.3x= 6120-5400
0.3x= 720
x=720/0.3
x= 2400
6000- x= 3600

Thirty percent of Irma’s Boutique’s sales came from leggings. They sold $390 worth of leggings last week. What were the total sa

RUDIKE [14]

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

$\frac{30}{100}x=390$

0.3x = 390

Dividing both sides by 0.3

$\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300$

Hence,

The total sales of Boutique last week = $1300
