A shopkeeper marks the price of an article
marin [14]

Answer:

The gain percent made by shopkeeper is 10.5%.

Step-by-step explanation:

Given:

Price at which goods are marked = 30%

Discount on the marked price = 15%

To Find:

Gain percentage of the shopkeeper

Solution:

Let the cost price of the product be = 100

Therefore,

MP = 30 + 100 = 130

Since discount is 15%. thus -

Discount = 15/100 x 130

= 19.5

Selling price = MP - Discount

SP = 130 - 19.5

= 110.5

Profit = SP - CP

= 110.5 - 100

= 10.5

Calculating the gain%

Gain% = 10.5/100 x 100

= 10.5

Answer: The gain percent made by shopkeeper is 10.5%.

The gcf of two numbers is 170. neither number is divisible by the other. what is the smallest these two numbers could be? (prime
ivanzaharov [21]

Answer:

340

Step-by-step explanation:

Given: GCF of two numbers is 170. neither number is divisible by the other.

To Find: smallest of these two number.

Solution:

As GCF of two numbers is 170, both number are divisible by 170.

Prime factor of 170 =2\times5\times17

multiples of 170 are 1\times2\times5\times17=170

                                           2\times2\times5\times17=340

                                           3\times2\times5\times17=510

GCF of all three multiples is 170,

Here 340 and 510 are the two multiples whose GCF is 170 and neither is divisible by other

Hence the smallest of two is 340, the answer is 340
