Answer 1

Answer :

➥ Ravish got 23.75% on the articles.

Given :

➤ Ravish bought 100 articles for Rs. 4000.

➤ Ravish sold 20 of them at the gain of 5%.

➤ The remaining articles to gain 20% on the whole$.$

To Find :

➤ At what gain percent must he sell the remaining articles to gain 20% on the whole.

Required Solution :

→ CP of 100 articles = Rs. 4000

→ CP of 1 article = 4000/100

→ CP of 1 article = Rs. 40

❍ In the Question we are provided that he sells 20 article at a gain of 5 %

Therefore, SP of 20 article :

→ SP of 20 articles = 40 × 20 + 40 × 20 × 5/100

→ SP of 20 articles = 800 + 800 × 5/100

→ SP of 20 articles = 800 + 8 × 5

→ SP of 20 articles = 800 + 40

→ SP of 20 articles = 840

He wants profit of 20% that means the profit he wants :

→ The profit he wants = 20/100 × 400

→ The profit he wants = 20 × 40

→ The profit he wants = Rs. 800

→ CP of 80 articles = 8 × 40

→ CP of 80 articles = Rs. 3200

He get Rs. 40 as a profit from Rs. 800

So, he want to get more Rs. 760

Now ,

⇛ Profit percent = Profit/CP × 100

⇛ Profit percent = 760/3200 × 100

⇛ Profit percent = 76/32

⇛ Profit percent = 23.75 %

║Hence, the Ravish got 23.75% on the articles.║

• Ravish sold 20 of them at a gain of 5%

To Find Out:-

Now,

Ravish wants profit of 20% that means the profit he wants :
