Answer 1

Answer:

50/3 %

Step-by-step explanation:

Answer 2

He must sell the remaining balls in 16.11% profit. ( approx )

Step-by-step explanation:

Given,

Total number of balls = 2000,

Cost price of all balls = rs 6000,

So, cost price of each ball = $\frac{\text{Total cost}}{\text{Total balls}}$

$=\frac{6000}{2000}$

= rs 3,

Now, if there is a gain of 5% in price of ball,

Then selling price = (100+5)% of 3 = 105% of 3 = $\frac{105\times 3}{100}=\frac{315}{100}=3.15$

If 200 balls are sold in this price,

Then revenue = 200 × 3.15 = rs 630,

Now, suppose remaining 1800 balls are sold in the profit of x%,

That is, selling price of each ball = (100+x)% of 3

So, the revenue = 1800 × (100+x)% of 3,

Thus, total revenue = 630 + 1800 × (100+x)% of 3,

According to the question,

Total profit percentage = 15%,

⇒ Total revenue = 115% of 6000

⇒ 630 + 1800 × (100+x)% of 3 = 115% of 6000,

⇒ 630 + 18 × (100+x)  × 3 = 115 ×60,

⇒ 630 + 54(100+x) = 6900,

⇒ 54(100+x) = 6270,

⇒ 100+x= 116.11,

⇒ x= 16.11,

Hence, he must sell the remaining balls in 16.11% profit.
