Question
have to take the three given statements to be true even
if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts. Statements: None of the rubber are boards. Every board is plants. Some plants are papers Conclusions: I. Few rubber are papers. II. Few papers are boardsSolution
None of the rubber are boards (E) + Every board is plants (A) β Some plants are not rubber (O*). Some plants are papers (I) β Conversion β Some papers are plants (I) + Some plants are not rubber (O*) β No conclusion. Hence neither conclusion I nor II follow.
If 64x3 - 343y3 = (4x - Ay) X (Bx2 + 49y2 + Cxy), then find the value of 3 X (2A + 6B) - 2C.
If a + b + c = 8, aΒ² + bΒ² + cΒ² = 18 and ab + b c+ ca = 12, then what is the value of aΒ³ + bΒ³ +cΒ³ β3abc?
If Β
Β = 4 then Β
(a + 7)2 + (b β 2) 2 + (c + 3) 2 = 0, then find the value of 3a - 2b + c.
Two positive numbers differ by 2, and the sum of their reciprocals is 3/4. What is the larger number?
(x + 1)2 + (y β 3) 2 + (z + 5) 2 = 0, then find the value of 2x + 3y - z.
If x + 1/x = 5, then x2 + 1/x2 is:
(x β 6) 2 + (y + 2) 2 + (z β 4) 2 = 0, then find the value of 4x - 3y + z.
22% of βxβ is equal to 66% of βyβ, then find the value of x: y.
