Find the gain percentage, given that Anubha sold her scooter for Rs.23,358 gaining \(\frac{1}{6}\)th of the selling price
For the equations ax + (a2 + 1)y = 4 and 4x + ay = a2, which of the following statements is TRUE?
If \(a = 6\), then \(x = \frac{325}{28},\ y = -\frac{25}{28}\) are the solutions.
If \(a = 6\), then \(x = 48,\ y = 4\) are the solutions.
If \(a = -12\), then \(x = \frac{325}{28},\ y = -\frac{25}{28}\) are the solutions.
If \(a = -12\), then \(x = 48,\ y = 4\) are the solutions.
In ΔPQR, if PT is the median, then which of the following is correct?
PQ2 + PR2 = PT2 + QR2
PQ2 + PR2 = 2(PT2 + QT2)
PQ2 + PR2 = 2(PT2 - QT2 )
PQ2 + PR2 = PT2 + QT2
