**** Price of a commodity is first increased by x% andthen decreased by x%. If the new price is K/100,find the original price.(a) (x - 100)100/K (b) (x2 - 1002)100/K(c) (100 - x)100/K (d) 100K/(1002 - x?) |
|
Answer» Answer: (d) Step-by-step EXPLANATION: LET the original price be a. When it is increased by x%: = > a + x% of a = > a(1 + x%) When decreases by x%: = > a(1 + x%) - x% of a(1 + x%) = > a(1 + x%){ 1 - x% } = > a{1² - (x%)²} {(a+b)(a-b)=a²-b²} In question, new price is k/100: = > a(1² - (x²/100)²) = k/100 = > a(100² - x²)/100² = k/100 = > a(100² - x²) = 100²k/100 = 100k = > a = 100k/(100² - x²) Original price was 100k/(100² - x²) |

Which of following is not irrational? (3+√7) (3-√7) (3+√7) (3-√7) (3√7) |
|
Answer» Question :- Which of following is not IRRATIONAL ? {(3+√7) (3-√7)} , or (3√7) ? Solution :- Solving First we get, → {(3+√7) (3-√7)} using (a + b)(a - b) = (a² - b²) we get, → {(3)² - (√7)²} Now using , (√a)² = a, we get, → (9 - 7) → 2 → (2/1) → in the FORM of p/q, where q ≠ 0. Therefore, {(3+√7) (3-√7)} is a rational Number.________________Now, Solving second part :- → 3√7 → 3 * √7 → 3 can be written as (3/1) , where denominator is not ≠ 0 , so a rational number). → √7 is a non perfect natural number . As we know that, any non non perfect natural number is always an irrational number). Therefore, → (Rational) * (Irrational) → Irrational Number. Hence, we can conclude that, {(3+√7) (3-√7)} is not an irrational number. _________________________Extra :-
__________________________Note :- { if we assume all parts of questions different, than, all are irrational numbers as TOLD in extra. } . |
