Answer» Question :– Find two NUMBERS WHOSE sum is 28 and product is 180. Solution :– Let, the first number be x. And the SECOND number be (28 - x). ATQ, → x(28 - x) = 180 After open the brackets we get, → 28x - x² = 180 → x² - 28x + 180 = 0 → x² - 10X - 18x + 180 = 0 → x(x - 10) - 18(x + 10) = 0 → (x - 10) (x - 18) = 0 → x - 10 = 0 OR → x - 18 = 0 So, First term :– • x - 10 = 0 • x = 10 Second term :– • x - 18 = 0 • x = 18 Hence, The required numbers are 10 and 18.

13977.

Find two numbers whose sum is 28 and product is 180

Answer»

Question :–

Find two NUMBERS WHOSE sum is 28 and product is 180.

Solution :–

Let, the first number be x.

And the SECOND number be (28 - x).

ATQ,

→ x(28 - x) = 180

After open the brackets we get,

→ 28x - x² = 180

→ x² - 28x + 180 = 0

→ x² - 10X - 18x + 180 = 0

→ x(x - 10) - 18(x + 10) = 0

→ (x - 10) (x - 18) = 0

→ x - 10 = 0

OR

→ x - 18 = 0

So,

First term :–

• x - 10 = 0

• x = 10

Second term :–

• x - 18 = 0

• x = 18

Hence,

The required numbers are 10 and 18.

13991.	A vendor bought 100 oranges for 200. He sold 20 of them at a gain of 5%. At what gain percent must he sell the remainder so as to gain 30% on the whole.
Answer» Answer 218 STEP by step explanation Cp of oranges = 200 profit on it, 30% of ₹200 = 30/100 × 200=60 TOTAL selling price = 200 + 60 = 260 Cp of 100 oranges = ₹200 Cp of 1 orange = ₹200÷100 = 2 Cp of 20 oranges = 2 × 20 = ₹40 GAIN on 20 oranges = 5 % of 40 Gain = 40 × 5/100 = ₹2 Total SP of 20 oranges = ₹40 + ₹2 = ₹42 SP of all the oranges with profit of 30% - SP of 20 oranges = SP of remaining oranges with profit I.e ₹260 - ₹42 = ₹218 So he should SELL it for ₹218 to get overall gain of 30%

13991.

A vendor bought 100 oranges for 200. He sold 20 of them at a gain of 5%. At what gain percent must he sell the remainder so as to gain 30% on the whole.

Answer»

Answer

218

STEP by step explanation

Cp of oranges = 200 profit on it, 30% of ₹200 = 30/100 × 200=60

TOTAL selling price = 200 + 60 = 260 Cp of 100 oranges = ₹200

Cp of 1 orange = ₹200÷100 = 2 Cp of 20 oranges = 2 × 20 = ₹40

GAIN on 20 oranges = 5 % of 40 Gain = 40 × 5/100 = ₹2

Total SP of 20 oranges = ₹40 + ₹2 = ₹42

SP of all the oranges with profit of 30% - SP of 20 oranges = SP of remaining oranges with profit

I.e ₹260 - ₹42 = ₹218

So he should SELL it for ₹218 to get overall gain of 30%
